摘要
临界大体积滑坡是岩土工程中经常遇到的不良工程地质问题,其成因及活动变形对确定治理方案有决定性作用。本文在大量勘探、试验及观测资料基础上,对云南务坪水库1#滑坡———临界大体积二级牵引式滑坡成因及后期活动变形特征进行分析研究,特别针对勘探过程中揭露的岩土工程地质特性,结合滑坡区域内形成的微地貌现象进行了综合分析,指出控制该滑坡后期活动变形和整体稳定的主要因素,并提出相应处理方案。经水库多年运行表明,处理结果合理可靠,滑坡处理是成功的。
Critical large-volume landslide is a common problem in geological engineering, and the causes of its formation and moving deformation have a decisive role for making treatment plan. In this paper, after a series of survey, tests and observations, the author analyze the causes of formation of 1^# landslide in Wuping Reservoir （a critical secondary drawing landslide with large-volume） and the features of its later-stage moving deformation. Aiming at revealing the geological features of geotechnics, a comprehensive analysis has been conducted by considering the micro-landforms of the landslide site. The main factors controlling later-stage landslide deformation and integral stability are discussed. A corresponding treatment plan has been proposed and put into practice. The Wuping Reservoir has been in safe operation for many years. This indicates that the treatment plan is reliable and successful.
