摘　　要：华莹山溪口滑坡是八十年代末期我国最大的地质灾害事件。与溪口滑坡一沟之隔的北侧斜坡，具有与溪口滑坡区相似的地形地貌特征，且在坡体后缘发现有多处弧形裂缝，其是否具失稳的可能性及是否会产生类似的溪口滑坡的灾害性破坏成了人们关注的焦点。本文在运用多种数值模拟方法详尽阐述溪口滑坡形成机制的基础上，对其旁侧变形体进行了综合对比分析，并提出了变形体的工程整治方案。Xikou landslide in Huaying mountain is a largest event of geological hazard in our country in the late of 1980's. After its occurrence, one has regard to the stability of an adjacert mountain mass, naturally, especially to that of the slope a gully apart form and to the north side of Xikou landslide. Since the slope is similar to Xikou landslide in geomorphological characteristics and there are arced fissures discovered in many places on the rear edge of the slope, whether the slope will lose its stability and result in a hazard, similar to that due to Xikou landslide, becomes a focus one concerns oneself with.Based on elaborating the mechanism of Xikou landslide by several simulation digital methods, this paper has made a combined contrast and analysis of the deformed mass adjacent to the landslide and presented a scheme of control works for the deformed mass.
