不同竖向荷载下PHC管桩水平承载性能研究

在桩基设计中通常分别确定单桩的竖向和水平向承载力,而不考虑竖向荷载与水平荷载之间的相互作用对桩承载力的影响,这显然不能反映桩的真实受力状况。本文通过现场的载荷试验,分析了PHC管桩在不同竖向荷载下的水平承载性能,利用有限元软件ANSYS对该实例进行数值模拟,结果表明：在先施加竖向荷载再施加水平荷载时,存在一个最优的竖向...

Research on the lateral bearing capacity of prestressed high-strength concrete pipe pile under different vertical load

It is a common practice to determine the vertical bearing capacity and lateral bearing capacity separately in the design of pile foundations without consideration of the interaction between the vertical and the lateral load.It would certainly not reflect the real conditions.This paper,based on the field load test,analyzes the lateral bearing capacity of prestressed high-strength concrete pipe pile under different vertical load;and the response of this test is simulated by the means of three-dimensional fini...
