雾化雨入渗对溪洛渡水垫塘区岸坡稳定性的影响

运用不平衡推力传递法编制了考虑非饱和带基质吸力和暂态附加水荷载等作用的岩坡稳定分析程序ZSLP。根据雾化雨模型试验结果和岸坡护面措施可能发挥的功效，拟定了12种分析工况。在12种雾化雨入渗工况下，用ZSLP程序对溪洛渡水垫塘区岸坡进行了稳定分析。分析结果表明，雾化雨入渗能显著降低岸坡的稳定安全系数，安全系数的降幅对护面措施的功效比较敏感，应重视控制雾化雨的入渗。

Influence of atomized rain infiltration on stability of cushion pool slope of xiluodu project

By use of the non-equilibrium push transmission method, a program for analyzing the stability of rock slope named ZSLP is worked out. The program can consider the functions of matrix suction and temporary additional water load. Based on the model experiment results of atomized rain infiltration and the possible efficacy of protective facing measures of bank slope, 12 kinds of analysis cases are drafted. Under these cases, stability analyses of cushion pool slope of Xiluodu project under the influence of atomized rain infiltration are done by use of the program ZSLP. The results show that atomized rain infiltration will bring harmful influence on the stability of bank slope; and the reduce range of safety factor is sensitive to the efficacy of protective facing measures. Therefore, control of atomized rain infiltration should be paid great attention to.
