摘　　要：嘉陵江亭子口电站大圆包崩滑体的稳定性问题是该崩滑体利用问题的关键。为了解决大圆包崩滑体的稳定性问题,对嘉陵江亭子口电站大圆包崩滑体进行了原状滑带土的室内物理力学试验研究以及三种不同性状的典型滑面的原位直剪试验研究。通过对试验成果及崩滑体性状进行综合分析认为:滑面的抗剪强度参数是崩滑体抗滑稳定性的控制性参数。在试验成果基础上,结合其它影响因素,提出了可供设计采用的滑面抗剪强度参数。The stability of the slide mass at Dayuanbao of Tingzikou Power station dictates the suitability of its utlization. In order to analyse the stability of the Dayanbao colluvial accumulation slide mass, indoor tests of physical and mechanical parameters for the original state soil, as well as in-site tests for three typical slide surfaces of Dayuanbao colluvial accumulation slide mass have been conducted. The compositive analysis of the test results and the colluvial accumulation slide properties reveal that： shear strength parameters of slide surface are the key parameters influencing the stability of the colluvial accumulation slide mass. Based on the test results and other influencing factors, the shear strength parameters of slide surface are suggested for the consideration by the designer.
