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。 In order to study the seismic behavior of prestressed pipe piles, the shaking table is used to analyze the stress, strain, moment and displacement of pipe pile-soil superstructure model under different seismic waves. , The location of the maximum moment and the stress and failure characteristics of pile and cap are obtained. The result shows that the maximum bending moment of pile under earthquake is located at 5 ~ 6 times of pile diameter from the top of pile, Under the El-centro wave, LWD wave and sine wave conditions, the response of the pile-superstructure system exhibits the “K” type distribution and other reaction rules in height.
