摘要
大河坝古滑坡东部前缘在暴雨季节发生了蠕滑变形,造成近十栋居民房屋及公路路基开裂,使人民生命财产受到严重威胁。根据对古滑坡的研究,将滑坡体分为未变形区、轻微变形区、弱变形区和强变形区四个区域,且对其稳定性进行了定性分析并进行了稳定性计算,结果表明,未变形区、轻微变形区整体处于稳定状态,强变形区所占比例甚小,失稳后损失小,仅需对弱变形区进行治理,就能保证滑坡体的稳定,节省了治理经费。
The creep deformation in the Daheba landslide has been observed during the rainfall season. It has caused the damage of some farmer's houses and the local road. After the geological research, the landslide is divided into no - deformation part, slight - deformation part, deformation part, and large - deformation part. The qualitative analysis and the quantitative calculation have been carried out, which shows that the no - deformation part and the slight - deformation part are stable as a whole, and only the deformation part is necessary to reinforce.
