摘要
古滑坡是斜坡长期复杂演化过程的产物,物质组成复杂、岩土力学性质特殊,具有极强的隐蔽性和扰动敏感性,古滑坡复活一直是困扰我国重大工程规划建设和城镇安全的突出问题。文章以黔东南州某办公楼西侧滑坡为例,通过调查、勘查、测绘、资料收集等勘查手段,从气象水文、地形地貌、地质环境条件、工程活动等方面分析复活的原因,通过圆弧滑动法评价其稳定性,并提出有效治理方案,为地方政府及广大地灾防治工作者提供参考。
Ancient slides are the product of long-term complex slope evolution.The slides with complicate composition,special geomechanical properties are well hidden and easily disturbed.Revitalizing of ancient slides has been always an outstanding issue for China’s major project planning and construction and urban safety.The paper analyzes the revitalizing cause of a slide in Nanzhou of East Guizhou in hydrology,meteorology,landscape and geology and engineering activity by investigation,exploration,mapping and data collecting,and evaluates the slide’s stability with circle method to propose effective treatment,so as to providing reference for local governments and geological disaster control workers.
