万州地区移民迁建工程建设中形成大量的人工高切坡。特定的岩性和地层组合使高切坡非常易于发生崩塌失稳,形成严重地质灾害。笔者运用工程地质分析方法,研究了万州地区高切坡地质特点和崩塌的影响因素,为高切坡的工程治理防护提供地质基础;从崩塌发生的力学本质出发,按崩塌形成力学机制对崩塌提出了不同于前人的新的崩塌分类方法;将崩塌发育过程划分为3个阶段,深化了对崩塌灾害发育演化过程的认识,为崩塌的监测、预警提供了理论基础。
Wanzhou area immigration relocation project in the formation of a large number of artificial high cut slope. The combination of specific lithology and formation makes the high cut slope very prone to collapse and instability, leading to serious geological disasters. Using engineering geology analysis method, the author has studied the geological characteristics of high cut slope and the influencing factors of collapse in Wanzhou area, and provided the geological foundation for engineering cutting protection of high cut slope. Based on the mechanics of collapse, the collapse mechanism was proposed based on the mechanism of collapse formation The new collapse classification method is different from the previous one. The collapse process is divided into three stages, deepening the understanding of the process of collapse and disaster evolution and providing a theoretical basis for the monitoring and early warning of collapse.
