ABSTRAK
Dengan semakin berkembangnya metode soil improvement, khususnya dengan menggunakan Prefabricated Vertical Drain (PVD), maka diperlukan perhatian khusus dalam menganalisa PVD. Pada umumnya kecepatan waktu konsolidasi dipengaruhi oleh jarak dan panjang PVD. Analisa yang digunakan biasanya menggunakan model konsolidasi 1 dimensi. Seiring perkembangan teknologi komputansi, perhitungan PVD dapat dilakukan dengan metode elemen hingga 3 dimensi. Model 3 dimensi memiliki keakuratan yang baik namun tingkat kompleksitas yang lebih tinggi. Perhitungan PVD pada umumnya menggunakan model 2 dimensi / plane strain model. Agar model 2 dimensi memiliki keakuratan yang baik diperlukan ekivalensi permeabilitas tanah asli dan jarak PVD. Penulis menitikberatkan kedua hal tersebut dengan harapan diperoleh model yang tepat dalam perhitungan PVD sesuai dengan kenyataan di lapangan

ABSTRACT
With the development of the soil improvement method, especially using prefabricated vertical drain (PVD) it is necessary to analyize accurately. Generally the rate of consolidation time depends on two factor, spacing and the length of PVD. One dimension consolidation calculation is often used to analyze PVD. With development in computation technology, PVD calculation can be done by finite element method three dimension which has good accuration but more complex. In fact, two dimension model used to calculate PVD in order to have good accuration the permeability of soil and the spacing of PVD must be equivalent with three dimension model. Thw writer will focus in these factors in hopes to obtain the right PVD calculation model accordance with the fact in field;

The book comprises select proceedings of the 2016 annual conference of the Indian Geotechnical Society (IGC 2016), with technical papers on the theme “Ground Improvement and Geosynthetics”. The papers cover a wide range of topics, including chemical modification using admixtures, microbial-induced carbonate precipitation, geopolymers, fly ash and other industrial wastes, modification using geosynthetic materials such as natural and synthetic fibers, expanded polystyrene (EPS) geofoam, prefabricated vertical drains, geosynthetic encased-granular columns and mechanical densification through sand columns. This book is a valuable reference for researchers and practicing engineers alike.
