| 摘 要： | 本文首先从地质背景、形态特征、滑面特征及水文地质等方面,对作揖沱崩滑堆积体的特征进行了概括。在总结已有研究成果的基础上,将降雨对斜坡稳定性的影响进行了定量确定,并在剩余推力法公式和程序中加入这些量化关系,对剩余推力法进行了改进。然后用试验、参数反演及综合经验等方法确定了作揖沱崩滑堆积体稳定性计算的参数,采用改进的剩余推力法与Sarma法对其进行稳定性计算,结果表明:降雨与库水位的提升对作揖沱崩滑堆积体稳定性的影响较大。最后,根据作揖沱崩滑堆积体失稳可能产生的危害,提出了相应的防治对策。

| Abstract: | The basic features of Zuoyituo landslide such as geological conditions, dimensions, sliding surface and groundwater conditions were described concisely in the paper. The effects of rainfall were categorized systematically based on the existing achievements, and the ways were given out to determine the effects quantitatively. The remained slip force method was improved by adding the quantitative relations into the existing formulas and programs. The parameters of the landslide were determined with some experiments, the method of back\|analysis and empirical data. The safety factors of Zuoyituo landslide were calculated with the improved remained slip force method and Sarma method. The results show that the rainfall and the rising of water level in Changjiang river have significant effect on the stability of Zuoyituo landslide. The hazards causing from the instability of Zuoyituo landslide were assessed, and the prevention methods were put forward. |
