| 摘 要： | 镇安场变形体位于长江左岸的重庆市涪陵区镇安场，是我国地质灾害多发地之一，主要表现为崩塌、滑坡、泥石流等地质灾害。该变形体变形的主要影响因素除地形地貌、地层岩性、物质结构外，还有瀑雨、洪水、地震、植被破坏等外在因素。通过野外勘查，运用探槽、浅井、钻探等工程控制，已查明该变形体已发生过局部变形，尚未形成大范围的变形和滑移，处于潜在滑移变形阶段。在三峡库区水位上升后，特别是在水库水位降低和地震作用下，变形体可能失稳而向下滑动。通过对变形体的稳定性的评价，认为该区沿库岸应采用以支挡工程为主、排水为辅的防治方案。

| Abstract: | Zhen'anchang deformation body in Zhen'anchang area Peiling District, Chongqing City located in the left bank of Cangjiang River. It's one of the places that the geologic hazards such as surface collapse, landsliding and debris flow often occur. Based on the geological survey, trenching, shallow bored welling and trilling, it is suggused that the deformation body had deformed partly, and now large scale deformation has not happened. The body is still in its latency sliping stage. After the water level in the Sanxia reservoir rises, especially it falls again, or if the earthquake takes place, the body will lose its steability and slips down. Apart from the topographty, physiognomy, stratum characters and structure, the main factors of effeting deformation are heavy rain, flood, earthquake, and the vegetation destroied badlly. According to the study on the steability of the deformation body, it is suggust that the project of mainly supporting and assistantly drainageing should be used along the bank of the reservoir to control the geological hazard happening. |
