【摘要】 总结地下水对土坡稳定性的多方面影响。认为土水间的相互作用影响土颗粒的性质；有效应力原理运用的关键，在于正确获得孔隙水压力；孔隙水压力并非不变的；给出土坡稳定性分析中对孔隙水压力和动水压力的近似计算方法。这些对提高土坡稳定性评价结果的可靠性至关重要。更多还原

【Abstract】 Multieffects of groundwater on earth slope stability analysis are systematically generalized. The results are as follows: the interaction between earth and groundwater influences the properties of earth granules; the key to apply the effective stress law is to get right pore water pressure; the pore water pressure is not permanent. At last, the approximate calculation methods of pore water pressure and flowing pressure are presented. These contribute to better reliability of slope stability analysis.更多还原
