... prototype conditions remains unclear, as existing studies have focused on small-scale 1-g model tests. This study conducted three centrifuge model tests on soil slopes reinforced with double-row micropiles and double/single-row MACS, respectively, based on a highway slope in Shandong, China. The development...

...Xianfeng Ma, PhD; Guohang Tang, Eng; Mingyang Cao, PhD; Yuxiang Zou, Eng; Haihua Zhang, PhD This study presents a series of centrifuge model tests that were conducted to investigate the grouting mechanism and its effect during rectangular pipe jacking in soft soil. A new jacking grouting device...

...Masaki Kitazume At present, centrifuge model testing has become an important tool for investigation of complex geotechnical natures. In 1980, the Port and Harbour Research Institute (PHRI) constructed the Mark I geotechnical centrifuge, whose effective radius was 3.8 m. Since then, the PHRI carried...

...M. Ruhul Amin Khan; Jiro Takemura; Osamu Kusakabe The behavior of double sheet pile wall cofferdam on a thick clay deposit subjected to a flash flood was studied through a series of centrifuge model tests. In a rectangular container a thick layer of kaolin clay was placed on a layer of fine silica...

... in centrifuge model tests. In the present study, model sandy ground was prepared by three techniques and their degrees of saturation were estimated by measuring the P-wave velocity propagating through the ground. The degree of saturation of model ground was greatly influenced by the preparation technique...

...Takeru Ariizumi; Hiromasa Igarashi; Shunsuke Kaneko; Hideki Nagatani; Takeshi Yamazaki; Osamu Kusakabe A series of centrifugal model tests was conducted to examine the long-term loads acting on a tunnel fixed in space in soft clay, experiencing long-term deformation. Two possible hydraulic boundary...

...Mohammod Ruhul Amin Khan; Jiro Takemura; Hiroki Fukushima; Osamu Kusakabe Behavior of double sheet pile wall cofferdam on sandy soil subjected to high water was studied through a series of centrifuge model tests. Model ground and fill of the cofferdam were made by fine silica sand in a rectangular...
