重庆巫山县城北门坡地段地质环境异常复杂，斜坡裂缝和崩滑灾害发育；斜坡下部位于长江三峡水库水位变动带，预测坍岸宽度可达190～300m。巫山县城为库区的全迁城镇，北门坡为新、老县城的复合部位，滑坡和坍岸的危害均十分严重。对此，根据防治对象的差异和技术、经济的可行性以及治理与开发利用相结合的原则，提出了北门坡地段滑坡、坍岸灾害的综合防治工程体系。
The geological environment of Beimenmeng section in Wushan county of Chongqing city is very complicated with the development of slope cracks and landslides. The lower part of the slope is located in the water level fluctuation zone of the Three Gorges Reservoir in the Yangtze River. The width of collapse bank is predicted to reach 190-300m. Wushan County is the relocated town in the reservoir area, and the north slope is a composite part of the new and old county towns. The landslides and the collapse of the bank are very serious. In this regard, according to the differences in prevention and control targets and the technical, economic feasibility and the principle of combining governance with development and utilization, a comprehensive prevention and control engineering system of landslides and bank collapse hazards in the north gate slope is proposed.
