摘要

为研究预应力管桩的抗震性能，采用振动台通过对管桩-土-上部结构模型在不同地震波作用下的试验，分析研究管桩桩身产生的应力、应变、弯矩及位移沿桩身的分布、最大弯矩产生的位置、桩与承台的受力及破坏特征，得出地震作用下管桩桩身弯矩最大值的产生位置为距离桩顶5～6倍桩径处

在El-centro波、LWD波和正弦波工况下，桩-上部结构体系的加速度反应在高度上呈现“K”型分布等反应规律及特征。

Abstract

In order to study the seismic performance of prestressed concrete pipe pile

the tests on pile-soil-structure model under different seismic waves on the shaking table are carried out to study the distribution of stress

strain

bending moment and displacements along the pipe pile. The position of maximum bending moment and the force and failure characteristics of the pile and the pile cap are also studied

so that the reaction rules and characteristics of the pipe pile under earthquake are obtained. Finally

some conclusions are drawn as follows. The maximum bending moment of the pipe pile is located at the distance of 5-6 times the pile diameter to the top of the pile under El-centro wave of LWD wave and sine wave conditions. The acceleration response of the pile -superstructure system is rendered in height "K"-type distribution

etc.
