某长大缓倾顺层边坡支护效果的离心实验研究

Centrifugal experimental study on the support effect of long and gently dipping bedded slope

为研究某长大缓倾顺层边坡的支护效果,通过对边坡开挖失稳阶段和双排桩支护阶段的离心模型实验,研究开挖失稳模型和双排桩支护模型的变形破坏规律。着重探讨了长大缓倾顺层边坡失稳原因和支护效果,实验结果表明:利用离心模型实验方法研究长大缓倾顺层边坡的支护研究是可行的;长大缓倾顺层边坡在降雨、开挖等诱发因素作用下是可能发生活动的;双排桩支护方法治理长大缓倾顺层边坡是有效的。

In order to study the support effect of a special slope which is longer,gentle dip and bedding,the centrifugal model test of the slope excavation instability stage and the double row pile support stage was carried out.Through the study of the deformation and failure of the excavation instability model and the double row anti-slide pile support model,the causes of the instability and the support effect of this special slope are discussed.The experimental results show that it is feasible to study the support of this kind of slope by centrifugal model experiment.This special slope may be active under the influence of induced factors such as rainfall and excavation.It is effective to control this kind of slope by the double row anti-slide pile support method.
