小东江电站左岸边坡稳定性分析及治理措施

Stability Analysis and Treatment measure for the Slope of the Left Bank of Xiaodongjiang Power Station

为了确定小东江电站左岸边坡体的稳定性状况,以边坡体工程地质条件为基础,对该边坡体的滑坡成因进行分析。通过运用极限平衡法和有限元法计算分析,边坡体可能产生蠕滑失稳,须进行加固治理。经综合比较分析,加固方式采用格构式加固体系更加合理,阐述了方案设计过程及格构梁与锚索(杆)的布置。加固的效果表明,分析计算及加固方案是合理的。

Based on engineering geologic condition, the cause of landslide is analyzed for the conforma tion and treatment of the stability of the slope. The result of calculating of the landslide mass＇ s stability with the method of limit and limit element method elicits the possibility of creeping slip and the need to reinforce it. By comparative analysing synthetically, the slope is reinforced reasonably by treillage of reinforcement system, at the same time , the course of calculation in schematic design and the layout of treillage beam and anchored cable（anchored bar） are introduced in detail. The effect of the treatment shows that the analysis and the treat ment to the slope is reasonable, which is referential to the other projects.
