Laboratory Model Test

Using similarity theory as guidance ,the paper designs the laboratory model test on foundation reinforcement by locating lime-soil pile at both side of strip footing, and researches foundation bearing capacity, p-s curve, the magnitude and distribution discipline of the foundation stress before and after reinforcement, and analyzes the load-bearing mechanism, strengthening mechanism and reinforcement effect of the strengthening technology. The results show that the lime-soil pile can effectively improve the foundation bearing capacity, and reduce the amount of ground settlement; under the role of the lime-soil pile, the stress spread lesser to the outside of pile in the ground, and causes the foundation stress to the deeper place.

Laboratory Model Test

Laboratory model test results for the ultimate bearing capacity of strip and square foundations supported by sand reinforced with geogrid layers have been presented. Based on the model test results, the critical depth of reinforcement and the dimensions of the geogrid layers for mobilizing the maximum bearing-capacity ratio have been determined and compared. Key words : bearing capacity, geogrid, model test, reinforced sand, shallow foundation.

Shaft Friction

A series of laboratory model tests and numerical analyses has been carried out to study the behaviour of vertically embedded cylindrical anchors in sand. Due to the cylindrical shape of the anchor, both the shaft friction and the end resistance have substantial contribution to the pullout capacity. But shaft friction and end resistance do not reach peak values at the same anchor displacement. As a result, analyzing the anchorage behaviour of cylindrical anchors is complicated. The pullout behaviour of the anchor is significantly influenced by the embedded depth. There exists a critical depth (about seven to eight times the anchor diameter D) which differentiates the behaviour of a deeply embedded cylindrical anchor from that of an anchor with shallow embedment. The complete load-displacement relationships for shallow and deep anchors can be simulated by the numerical analysis proposed herein. A minimum horizontal spacing of 10D is needed between neighbouring cylindrical anchors to be free of interference.Key words: cylindrical anchor, uplift behaviour, laboratory model test, numerical analysis, sand.
