摘要
针对成层地基中薄壁管桩受水平荷载的问题,基于有限元理论,编制了薄壁管桩全桩位移和内力的计算程序,利用该程序结合工程算例对影响薄壁管桩水平承载性状的因素进行了分析.结果表明:桩径是影响薄壁管桩水平承载性状的主要因素,其次是桩长和地基土性质,而桩身刚度和桩身壁厚的影响相对较小.
A program for calculating displacement and intemal forces of thin-wall pipe piles under lateral loads in layered soil was provided based on finite element theory. Its application in a project shows that, of the main parameters affecting the behavior of pipe piles, the most important factor is pile diameter, followed by pile length and property of ground soils, and the influences of rigidity and wall thickness of piles are relatively low.
