With the project of the Taizisang Slope at the Shuibuya Hydropower Station as an example, an approach is presented to analysis of the stability of the unsaturated soil slope under the action of atomized rain. The fuzzy synthetic evaluation method is used to evaluate the atomized rain intensity of jet overflow; the finite element method is used to simulate the atomized rain infiltration induced saturatedunsaturated seepage flow fields; the finite differential method is used to analyze the slope stability under the infiltration. In calculation, the analyzed results of the former stage are used in analysis of the later stage, and the FEM mesh and the seepage fields obtained in seepage analysis are directly used in the FDM Code for stability analysis, thus improving the analytic precision of seepage forces. The analyzed result and practical situation are in good agreement.
