摘要

为了研究冠梁约束型抗滑桩在振动作用下的抗震性能

以大型振动台试验为手段

对比研究了冠梁约束型抗滑桩和普通抗滑桩在不同El地震波作用下的动力响应

结果表明:（1）随着El波加速度峰值的不断增大

抗滑桩桩身放大系数增大及桩身动土压力随之增大。（2）由于冠梁的作用

使得冠梁约束型抗滑桩联合成整体受力

改变了抗滑桩结构的受力条件。（3）X向加载时

冠梁约束型抗滑桩桩顶放大系数相对于普通抗滑桩较大;Z向加载时

恰好相反;双向加载时

其桩顶放大系数的差值与峰值加速度相关。（4）随着振动的加剧

在基岩接触面可能产生新的剪切滑移线。（5）在振动作用下

El地震波峰值加速度不超过1.2g时

冠梁约束型抗滑桩抗震性能相对较好。该试验可为震区抗震设计提供参考。

Abstract

In order to study the seismic performance of pile top combined beam structure under vibration

with large shaking table test as a means

we compare and study the dynamic response of anti-slide pile with pile top and coupling beam and ordinary anti-slide pile under different El Centro seismic ground motion

and draw the following conclusions:（1）With the increase of the peak value of El Centro ground motion

the anti-slide pile side amplification coefficient and the pile side earth pressure constantly increase.（2）Due to the effect of the crown beam

the force condition of anti-slide pile structure is changed.（3）Under the action of vibration in X direction

the amplification coefficient at the top of anti-slide pile with crown beam is larger than that of the top of ordinary anti-slide pile;Under the action of vibration in Zdirection

there is a contrary result;Under the action of vibration in XZdirection

the difference of the amplification factor of the different kinds of piles top is related to the peak acceleration.（4）With the increase of vibration

a new shear slip line may be produced in the bedrock surface.（5）Under the action of vibration

when the El Centro seismic peak acceleration is not more than 1.2g

the seismic performance of the constrained anti-slide pile is relatively better.This experiment can provide a reference for design of anti-seismic structure.
