泄洪雨雾入渗对雾化区边坡的影响分析

泄洪雨雾入渗导致的边坡稳定问题随着高坝大库的建设越来越突出，对此类问题的研究和认识大多停留在对岩土体强度降低和荷载增加两者之一上，对渗流和应力变形的耦合作用认识和应用不足。本文通过理论分析，对泄洪雨雾入渗的渗流分析中入渗边界条件重新做了界定，并指出了存在的问题；同时对应力变形计算中渗流荷载的增加和岩土体在非饱和区的强度变化，提出了自己的观点，并指出存在的误区。最后作者通过某一水电工程泄洪雾化区边坡的渗流和应力变形作了计算，得到了合理的计算结果。

Research on infiltration effect of atomized rain on slope

With the construction of high dams with large reservoir in China,the stability problem of slopes lied under atomized rain are serious.Atomized rain usually lasts rather a long time with heavy precipitation,under which it is very difficult to maintain the slope stability.The strength reduction of geomaterial or the load increase under the slope is the mechanism which causes the slope failure.However,the coupling action is less considered.Based on the theoretical analysis,two suggestions are made,the infiltra...
