斜坡基桩水平极限承载力及影响因素模型试验和数值模拟
Model test and numerical simulation of horizontal bearing capacity and impact factors for foundation piles in slope
摘要
Abstract
The foundation pile in the slope soil has the dual function of load-bearing and slip resistance. The horizontal force character of it is more complex than the pile in the flat ground. Numerical experiments and model tests are used to study bearing characters and influence factor. Results of the model test show that the distance from the top of the slope has a great impact on horizontal bearing deformation properties of the pile. Under the same level of the load, the horizontal displacement of the pile with a bigger distance is less than that of the pile with a smaller distance. The critical load and ultimate bearing capacity of the pile with a bigger distance is larger than that of the pile with a smaller distance. The result of numerical simulation shows that the horizontal ultimate bearing capacity decreases with the increase of the slope ratio and increases with the growth of the distance from the top of the slope, which is same as the result of model tests. Differences between horizontal bearing deformation properties of piles in the slope and piles in the flat ground are discussed and the calculation method of horizontal bearing capacity of pile in the slope is developed, which can provide a reference to specification revision and engineering design.关键词
