山东邹城雨山村西南滑坡灾害特征与防治方案
|
摘要
山东邹城雨山村西南滑坡在20世纪50年代发生过滑动,导致部分农田被毁。该滑坡为浅层土质滑坡,滑体成分主要为含碎石粉质粘土,滑带位于含碎石粉质粘土层与基岩接触带,由于人工切坡,滑带在滑坡前缘局部已揭露,滑床为下伏强风化闪长岩。近年来,频繁的人类工程活动导致该滑坡存在重新滑动的可能,为消除该地质灾害隐患,采取了悬臂式挡墙支挡和截排水结合的防治方案,达到了治理效果。
The landslide happened in the southwest of Yushan Village in Zoucheng of Shandong in 1950 s,some farmland was destroyed. It was a shallow soil landslide,the landslide mass was mainly pebbly-clay; the sliding zone was located in the pebbly-clay and bedrock contact zone. Due to the artificial slope cutting,the sliding zone in the front had been exposed,and the sliding bed was underlying strong weathered diorite. In recent years,frequent human engineering activities may lead to the landslide reoccurring. In order to eliminate the risks of geological disasters,the combined control plan with cantilever retaining wall and water interception & drainage system was taken to achieve the control effect.
