【摘要】 针对顺层岩质高边坡稳定性问题,提出了基于变温相似材料的降强法与倾斜抬升超载法相结合的综合法模型试验方法,推导了边坡稳定的地质力学模型综合法安全系数表达式,并将其应用到某典型顺层岩质边坡工程实例中,对其地质缺陷较集中的I5剖面开展综合法模型试验,获得了边坡的变形特征和破坏过程,揭示了边坡破坏模式为滑移-拉裂破坏,确定了边坡整体稳定综合法安全系数为KSC=1.526~1.575。更多还原

【Abstract】 Aiming at the problem of stability of bedding high rock slope,the comprehensive test method combined with strength reduction based temperature analogous material and overloading method by obliquely lifting frame was proposed.And the comprehensive safety factor was deduced to apply in the typical bedding rock slope engineering.The research of comprehensive method on the profile I5 that reflects the concentrated geological defects gains the deformation characteristic and failure process,and it reveals that the failure mode is sliding and fracturing.Finally,the comprehensive safety factors KSCby the geo-mechanical experimental test is in the range of 1.526 and 1.575.更多还原
