prediction of vertical Band Drain performance by the finite element method
Geotextiles and Geomembranes, 1993Co-Authors: D T Bergado, K Mukherjee, Marolo C Alfaro, A S BalasubramaniamAbstract:Abstract This paper presents the predictions of the performance of vertical-Band Drains (i.e. AliDrains) on soft Bangkok clay under full-scale embankment loading in the field and during large-scale consolidation with a Drain by using a reconstituted sample in the laboratory. A finite-element model of transient- and axisymmetric-flow problems considering equal strain was used. The numerical model also included the smear effects. The predicted data were compared with the laboratory- and field-test results. Laboratory consolidation tests using a Rowe cell and an oedometer apparatus were performed to obtain the compressibility parameters. By using a value of kh/ks of together with ds=2dm, the predicted results agreed with the field performance of the vertical Drains. In the laboratory, by using a reconstituted clay specimen, better predictions were obtained with kh/ks=2 and ds=2ds. Thus, the prediction by means of an equal-strain finite-element model was found to be satisfactory for the performance of vertical-Band Drains on soft Bangkok clay provided that the disturbance due to its installation was taken into account.

perencanaan perbaikan tanah dengan preloading prefabricated vertical Drain dan geotextile pada lapangan penumpukan petikemas di terminal petikemas trisakti studi kasus lokasi eks hendratna banjarmasin
2017Co-Authors: Mufidatul RochmahAbstract:Perluasan perlabuhan Trisakti Banjarmasin dilakukan karena jumlah barang yang keluar masuk melalui petikemas mengalami peningkatan terus menerus di setiap tahunnya. Pada tahun 2012 Arus petikemas tercatat sebanyak 384.323 boks atau 419.335 TEUs, jika diBandingkan dengan tahun 2011 terjadi kenaikan sebesar 15%. Peningkatan kapasitas pelayanan Pelabuhan Trisakti dimulai dengan memperluas lapangan punumpukan petikemas. Total luas lapangan punumpukan petikemas ± 2 ha. Dari hasil penyelidikan tanah yang dilakuakan PT Hutama Karya didapatkan hasil bahwa perluasan lapangan punumpukan petikemas terletak diatas tanah lempung lunak yang tebal. Melihat kondisi tersebut maka diperlukan perbaikan tanah dasar. Metode yang digunakan adalah preloading atau pra-pembebanan, PVD (Prefabricated Vertikal Drain) dan geotextile. Dari hasil perencanaan disimpulkan bahwa: elevasi timbunan awal +2.50 mLWS dan elevasi timbunan akhir +5.50 mLWS dengan beban total timbunan sebesar 12.924 t/m2, sedangkan PVD yang digunakan adalah PVD jenis SPB Prefabricated Band Drain dengan diameter 100 mm, ketebalam 4 mm, panjang 31 m, jarak pemasangan antar PVD 0.75 m dan pola pemasangan menggunakan pola segiempat. Penimbunan tanah dilakukan secara bertahap dengan kecepatan 50 cm/minggu. Untuk perkuatan timbunan digunakan geotextile jenis Stabilenka dengan jumlah lapisan sebanyak 4 lapis, diantaranya: Internal stability sebanyak 2 lapis, Foundation stability sebanyak 1 lapis dan Overal stability sebanyak 1 lapis
