摘要

中文摘要: 针对裂隙密度较大的岩体，利用等效连续介质理论，建立了裂隙岩体在雾化雨入渗下的饱和－非饱和渗流数学模型。根据雾化雨模型试验，选定雾化雨的强度。结合自然降雨，对裂隙岩体岸坡进行了雾化雨入渗的数值分析。分析结果显示，相对与薄雾区和自然降雨区，暴雨区的孔隙水压力升高较快，易形成对边坡稳定不利的暂态饱和区。因此，暴雨区的坡面防护和坡内排水应给予重视。

Abstract

Abstract:Aimed at densely fractured rock masses

the paper sets up the saturated unsaturated seepage flow mathematic model for atomized rain infiltration using equivalent continuum theory. Atomized rain strengths are selected according to the model experiment. Combined with natural rainfall

numerical analysis on atomized rain infiltration in fractured rock slope is conduced. The results show that pore water pressure increases quickly and transient saturated zone which is disadvantagous to the slope stability is easily formed in great storm zone

relative to thin frog zone and natural rainfall zone. So slope surface protection and inside bailing within great storm zone should be emphasised.
