Flexible barriers undergo large deformation to extend the impact duration, and thereby reduce the impact load of geophysical flows. The performance of flexible barriers remains a crucial challenge because there currently lacks a comprehensive criterion for estimating impact load. In this study, a series of centrifuge tests were carried out to investigate different geophysical flow types impacti...

Determination of the pile capacity is always a major concern for the safe geotechnical engineering design. Different direct and indirect methods have been proposed for determining pile bearing capacity such as static and dynamic approaches. Each method depends on the condition of the soil and type of pile as well as accessibility to necessary information. In this study bearing capacity of drive...

Abstract Bidirectional static load tests to evaluate the axial load-bearing capacity of large cross-sectional bored piles are indispensable. Nonetheless, this test is complicated, costly, and easy fail. A case history a bidirectional conducted in HoChiMinh City reported analyzed. In particular, pile with 1.8m diameter ∼60m embedment length, located Tan Binh district, City, tested using test. Th...

The results of an ongoing FEM parametric study are presented regarding the dependence of the resulting piled raft behavior under lateral load and combination of loads on pile diameter, pile length, arrangement of piles and raft thickness. Taguchi method with Analysis of Variance (ANOVA) was employed to calculate the contribution ratio of these factors on the lateral displacement of piled raft. ...

A vertical electro-osmosis method was proposed to improve the bearing capacity of piles in marine soft clay foundations. top-down test conducted by setting an anode and cathode at top bottom pile, respectively, while settings bottom-up were set opposite way. At same time, a pile without also up for comparison. The variation law water content, discharge volume, soil pressure, surface settlement ...

Reducing the settlements of soft foundation effectively is a critical problem of high-speed railway construction in China. The new CFG pile-slab structure composite foundation is a ground treatment technique which is applied on CFG pile foundation and pile-slab structure composite foundation. Based on the experience of constructing Beijing-Shanghai high-speed railway in China, the settlement-co...
