重庆市巫山县城北门坡地质灾害发育特征及工程防治方案研究

Study on Developing Features and Control Engineering Schemes of Geological Hazards in Beimenpo, Wushan County Town, Chongqing City

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。

In the section of Beimenpo, Wushan county town, Chongqing City, the geolog-ical environment is very complex and bad; slope cracks, collapses and landslides are devel-oped; the lower part of the slope locates in water level change belt of the yangtze river Three Gorges reservoir; predicted width of bank caving will be up to 190 m～300 m. Wushan county town is a complete migrated town in the reservoir area; Beimenpo slope locates in compound section of new and old county town, the harm of the landslides and bank cavings will be very serious. As a result, on the basis of difference of control object, possibility of technology and economy, and principle of control combined with exploit, the synthetical system of control engineering of landslide and bank caving bazards in Beimenpo section is raised.
