在对陈家坡滑坡进行现场地质勘查、现场试验及室内试验的基础上，详细阐述了滑坡基本特征、分析了其形成机制与演化过程。并用极限平衡法和数值模拟法对该滑坡在不同工况下的稳定性进行计算和评价。研究结果表明：天然状态下处于稳定状态，稳定性系数为1.168；暴雨状态下处于欠稳定状态，稳定性系数为1.05；地震状态下（Ⅷ级）处于基本稳定状态，稳定性系数为1.065。两种方法计算滑坡稳定系数结果是基本一致的。

Based on geological investigation, field tests and laboratory tests for Chenjiapo Landslide, the paper elaborated the basic characteristics of landslide, its formation mechanism and evolution. Moreover, the slide stability under different working conditions was calculated and evaluated by limit equilibrium method and numerical simulation. The results show that the landslide is in the steady state under the natural state, and its stability coefficient is 1.168; the landslide is in the less stable state under rainstorm state, and its stability coefficient is 1.05; the landslide is in the basically stable state under seismic loading with magnitude VIII, and its stability coefficients is 1.065. The result of stability coefficients obtained by limit equilibrium method and numerical simulation are mostly consistent.
