扭矩作用下嵌岩桩桩顶内力分布的模型试验

Model simulation of internal load distribution in rock-socketed piles subject to torsion

基于扭矩荷载下的 8组模型试验的实测资料 ,分析了扭矩作用下嵌岩桩基的实测桩顶内力、各桩位移抗扭力矩及转动抗扭力矩的变化及其分布规律。

On the basis of the measured data from model simulation tests on rock socketed pile groups subject to torsion, the variation and distribution laws of the measured forces in pile top, torsional moment against displacement and torsional moment against rotation are analysed. The testing results are coincident with those obtained from rigid loading stand assumption.
