摘要

摘要: 通过土工离心模型试验,施加 95<>g 离心加速度,研究桩基在不同水平加载高度下,加载高度对桩基水平承载力、位移、弯矩、桩身倾斜程度等的影响,通过对水平加载高度 <> h =159 mm , <> h =135 mm 两组离心模型试验数据的对比分析,发现在相同位移条件下桩基水平承载力随加载高度的增加而减小；在相同荷载条件下桩基弯矩、倾斜程度、位移随加载高度的增加而增加。

Abstract: Through centrifugal model tests, 95<>g centrifugal acceleration is applied for studing the effects of loading points on horizontal bearing capacity, displacement, moment and inclination of piles at different loading points. After comparative analysis of two groups of model tests with horizontal loading point <>h=159 and <>h=135 mm, it is found that the horizontal bearing capacity of the piles decreases with the increase of the horizontal loading point under the same displacement conditions, and the pile foundation moment, inclination and displacement increase with the increase of the horizontal loading point under the same loading conditions.
