在充分考虑滑裂面阻滑力影响的基础上，建立拱坝拱座滑体区域三维地质模型，进行三维极限平衡分析。在不同高水位工况下，分析地质结构面发育特征及其与坝体空间位置关系，获取危险滑块组合，得出块体要素及地质条件等相关数据，保证抗滑稳定计算边界条件的精准度。同时，将平面地质解析结果三维数字化，可直观表达危险滑块的稳定性与地质构造的关联性，便于拱座稳定与地质条件的综合分析。淋溪河水电站拱坝实际工程应用表明，该方法对拱座的抗滑稳定分析结果合理有效。

Taking the effect of sliding force of block boundary surface into a full consideration, the 3D geological model of sliding zone of arch dam support is built and the 3D limit equilibrium analysis is conducted. Then the structural surface development and its relationship with the spatial position of dam under different high water level conditions are analyzed, and the dangerous slider combinations are educed with its block elements and geological conditions which can guarantee the accuracy of boundary conditions for anti-sliding stability calculation. Meanwhile, the plane geological analytical results are digitalized in a 3D environment which can directly express the relationship between the stability of dangerous slider and geological structure and is convenient for a comprehensive analysis of arch support stability and geological conditions. The application of this method in the anti-sliding stability analysis of Linxihe Arch dam illustrates that the method is reasonable and effective.
