2.3.1

Specific Gravity

Specific gravity dari tanah, Gs, didefinisikan sebagai perbandingan massa volume partikel tanah di udara dengan massa volume yang sebanding dengan gas free distilled water di udara pada suhu kamar (umumnya 68 F {20 C}). Specific gravity ditentukan berdasarkan jumlah dari pycnometer yang sudah dikalibrasi, dimana massa dan suhu dari contoh tanah deaerasi/air distilasi diukur. Test dilakukan berdasarkan ASTM D 854-92, Standard Test Method for Specific Gravity of Soils. Metoda ini digunakan pada contoh tanah dengan komposisi ukuran partikel lebih kecil daripada saringan No. 4 (4.75 mm). Untuk partikel dengan ukuran lebih besar dari saringan tersebut, prosedur pelaksanaan mengacu pada Test Method Specific Gravity and Absorption of Coarse Aggregate (ASTM C 127-88). Specific gravity dari tanah diperlukan untuk menentukan hubungan antara berat dan volume tanah, dan digunakan untuk perhitungan test laboratorium lainnya.

2.3.2

Water Content / Moisture Content

Moisture content, w, didefinisikan sebagai perbandingan antara berat air di dalam contoh tanah dengan berat partikel solid. Contoh basah mula-mula ditimbang, kemudian dikeringkan di dalam oven pada suhu 230 F (110 C) hingga mencapai berat konstan. Berat contoh setelah dikeringkan adalah berat partikel solid. Perubahan berat yang terjadi selama proses pengeringan setara dengan berat air. Untuk tanah organik, terkadang disarankan untuk menurunkan suhu pengeringan hingga mencapai 140 F (60 C). Test dilakukan mengacu pada ASTM D 2216-92, Test Method for Laboratory Determination of Water (Moisture) Content of Soil and Rock. Moisture content diperlukan untuk menentukan properties tanah dan dapat dikorelasikan dengan parameter-parameter lainnya.

2.3.3

Analisis Saringan dan Hidrometer

Test ini dilakukan dalam dua tahapan, yaitu: analisis saringan untuk tanah berbutir kasar (pasir, kerikil), dan analisis hidrometer untuk tanah berbutir halus (lempung, lanau). Tanah yang mengandung butiran kasar dan butiran halus di uji secara berurutan. Material dengan ukuran lebih kecil dari saringan No. 200 (0.075 mm atau lebih kecil) dianalisis dengan menggunakan hidrometer. Analisis saringan memberikan pengukuran secara langsung terhadap distribusi ukuran partikel tanah dengan cara melewatkan contoh pada sejumlah wire screens, dari ukuran yang terbesar hingga terkecil. Jumlah material yang tertahan di tiap-tiap saringan kemudian ditimbang. Prosedur pelaksanaan pengujian ini mengacu pada ASTM C 136-95a, Method for Sieve Analysis of Fine and Coarse Aggregates. Pelaksanaan uji hidrometer mengacu pada Hukum Stokes. Diameter partikel tanah didefinisikan sebagai diameter bola yang memiliki unit massa dan kecepatan jatuh yang sama dengan partikel tanah. Jadi distribusi ukuran partikel didapatkan dengan menggunakan sebuah hydrometer untuk mengukur perubahan specific gravity, suspensi tanah-air seperti partikel tanah mengendap. Hasil analisis dicatat dalam combined grain size distribution plot sebagai persentase contoh yang lebih kecil beratnya versus log diameter partikel. Data ini diperlukan di dalam klasifikasi tanah. Kurva tersebut juga dapat menunjukkan parameter-parameter lainnya, seperti diameter2-5

efektif (D10) dan koefisien uniformity (Cu). Test dilakukan berdasarkan ASTM D 422-63 Method for Particle Size Analysis of Soils, dan ASTM D 1140 92 Test Method for Amount of Material in Soils Finer than the No.200 (75-m) Sieve.

2.3.4

Atterbergs Limit

Liquid limit dilakukan dengan cara meletakkan pasta tanah dalam mangkuk kuningan kemudian digores tepat ditengahnya dengan alat penggores standar. Dengan menjalankan alat pemutar, mangkuk kemudian dinaikturunkan dari ketinggian 0.4 inci (10 mm) dengan kecepatan 2 drop/detik. Liquid limit dinyatakan sebagai moisture content dari tanah yang dibutuhkan untuk menutup goresan yang berjarak 0.5 inci (13 mm) sepanjang dasar contoh tanah dalam mangkuk sesudah 25 pukulan. Pengujian dilakukan menurut ASTM D 4318. Plastic limit ditentukan dengan mengetahui secara pasti moisture content terkecil, dimana material dapat digulung hingga diameter 0.125 inches (3.2 mm) tanpa mengalami keretakan. Pengujian dilakukan sesuai dengan ASTM D 4318-95, Test Method for Liquid Limit, Plastic Limit and Plasticity Index of Soils. Shrinkage limit (SL) didefinisikan sebagai water content maksimum dimana pengurangan water content tidak akan menurunkan volume dari massa tanah. Pengujian dilakukan dengan mengacu pada ASTM D 427-93, Test Method for Shrinkage Factors of Soils. Nilai-nilai ini digunakan didalam klasifikasi tanah dan dapat dikorelasikan dengan parameterparameter lainnya.

2.3.5

Triaxial-UU

Tujuan test ini adalah untuk memperoleh parameter kekuatan tanah dalam kondisi undrained. Pada uji ini contoh yang diuji tidak diperkenankan untuk mengalami konsolidasi akibat tekanan confining dan selama geser berlangsung tidak diperkenankan adanya aliran (undrained). Dibutuhkan minimal tiga buah pengujian dengan tekanan confining yang berbeda-beda untuk mendapatkan parameter tegangan total. Jika selama pengujian tekanan air pori diukur, maka parameter tegangan efektif juga dapat diukur. Pengujian dilakukan menurut ASTM D 2850-95, Test Method for Unconsolidated, Undrained Compressive Strength of Cohesive Soils in Triaxial Compression.

2.3.6

Consolidation Test

Test ini bertujuan untuk memperoleh nilai koefisien konsolidasi Cc dan Cv yang selanjutnya dipergunakan untuk memprediksi lamanya konsolidasi dan besarnya settlement. Metode yang digunakan dalam pengujian konsolidasi adalah pengujian konsolidasi satu dimensi. Pada uji ini spesimen diletakkan pada konsolidometer (oedometer) diantara dua batu pori sehingga memungkinkan terjadinya drainase. Berbagai prosedur pembebanan dapat digunakan selama pengujian. Pengujian dengan peningkatan pembebanan adalah yang paling umum digunakan. Pada prosedur ini, spesimen diberikan beban yang semakin bertambah. Biasanya beban awal yang digunakan besarnya 1/16 tsf (5 kPa) dan ditambah menjadi dua kalinya hingga mencapai 16 tsf (1600 kPa). Setelah pemberian beban, perubahan tingga sampel dimonitor umumnya selama 24 jam. Untuk mengevaluasi parameter rekompresi, siklus pembebanan unload/reload dapat dilakukan selama pembebanan. Agar diperoleh hasil pengamatan parameter rekompresi yang lebih baik untuk lempung terkonsolidasi berlebih (over consolidated clay), siklus2-6

Laporan Akhir Penyelidikan Tanah dan Analisis Geoteknik Detail Desain Kolam Renang di Tanjung Redeb - Berau, Kalimantan Timur

unload/reload dilakukan setelah tekanan pra konsolidasi terdefinisikan. Setelah beban maksimum tercapai, beban dikurangi secara bertahap. Pengujian dilakukan menurut ASTM D 2435-90, Test Method for One Dimensional Consolidation Properties of Soils. Data dari uji konsolidasi biasanya ditampilkan dalam grafik e-log p dengan plot angka pori (e) sebagai fungsi dari logaritma tekanan (p) atau dalam grafik -log p dimana adalah regangan dalam %. Parameter-parameter yang diperlukan untuk perhitungan penurunan dapat diperoleh dari kurva ini adalah: indeks kompresi (Cc), indeks rekompresi (Cr), tekanan pra konsolidasi (Po atau Pc) dan angka pori awal (eo).

Korelasi Parameter Tanah

Parameter tanah ditentukan berdasarkan hasil penyelidikan tanah. Pada kondisi dimana tidak terdapat hasil pengujian tanah atau properti tanah sulit diukur secara langsung, parameter tanah ditentukan berdasarkan engineering judgment maupun korelasi terhadap properti tanah. Korelasi properti tanah disajikan dalam Gambar 3-10 dan Gambar 3-11.

ANALISIS PENURUNAN 1-D KONSOLIDASI TERZAGHI

Settlement dari suatu lapisan tanah yang dibebani dapat dibedakan menjadi 2 (dua) jenis, yaitu : immediate/elastic settlement dan consolidation settlement. 3.4.1 Immediate atau Elastic Settlement (Si)

Elastic settlement dari tanah terjadi sewaktu atau setelah masa konstruksi suatu struktur. Persamaan untuk mengevaluasi besarnya elastic settlement rata-rata dari pondasi fleksibel di tanah lempung jenuh (saturated clay) menurut Janbu, Bjerrum, dan Kjaernsli adalah sebagai berikut: Si dimana, qo Es A1 A2 = = = = beban luar Youngs modulus koefisien modifikasi sebagai fungsi dari H/B koefisien modifikasi sebagai fungsi dari Df/B =A1 A 2 qo B Es

Berdasarkan kondisi aktual di lapangan, elastic settlement pada lokasi kolam renang dapat diantisipasi dengan penimbunan kembali lokasi tanah yang sebelumnya digali untuk kebutuhan konstruksi, hingga mencapai kedalaman yang diinginkan (levelling). 3.4.2 Consolidation Settlement (Sc)

Consolidation settlement merupakan settlement yang bergantung pada waktu dan terjadi sebagai hasil dari pengaliran air pori dari rongga yang berada pada tanah lempung jenuh (saturated clayey soils). Pengaliran air pori dari rongga terjadi saat tanah lempung jenuh dikenai beban tambahan. Persamaan settlement konsolidasi satu dimensi adalah sebagai berikut :
