【摘要】 本文以汉源背后山滑坡为依托(采用锚索抗滑桩加固),共设计了无加固基准边坡和锚索抗滑桩单、排桩加固边坡三组离心振动台试验,旨在研究在地震作用下,抗滑桩桩前、桩后动接触应力分布规律和锚索拉力变化情况。本文详细介绍了该离心振动台试验的设计过程,包括模型相似关系设计、试验设备装置的选用、模型材料的选取、边坡模型的制备、加载方案设计、传感器的布置和试验方案的确定及试验前各项准备工作。本文所介绍的模型设计思路、制作过程及试验方案的确定,对今后的相关试验工作具有一定的参考作用和指导意义。更多还原

【Abstract】 In this paper,based on Beihou mountain landslide( reinforced by anchor-stabilizing piles),we design three centrifugal shaking table tests consisting of no reinforcement standard slope and slope with anchor-stabilizing piles to study the distribution law of contact stresses in front or back of stabilizing piles. The design process of the centrifugal shaking table test is introduced in detail,including similitude-scaling relationship determination,device selection,and model material selection,preparation of slope model,loading project,sensor placement,test program design and other preparation work. The method used in model test program design of this anchor-stabilizing pile will be helpful to other experimental studies.更多还原
