【摘要】 中国地质环境监测院在四川雅安峡口滑坡开展监测预测示范,已建立了包括地面位移监测、地下位移和裂缝监测、地下水监测和降雨监测的多参数监测系统,采用了包括GPS、GIS和自动监测技术在内的新技术方法。本文分析了峡口滑坡蠕变体水文地质与工程地质条件,运用FLAC软件分别对天然条件下和饱水条件下峡口滑坡蠕变体的变形情况进行了定量分析计算,揭示了滑坡蠕变体的变形特征和变形机制,为滑坡的评价提供了依据。更多还原

【Abstract】 Model zone construction of monitoring and predicting has been conducted in Xiakou landslide,which is in Ya’an City,Sichuan Province.Multi-parameter monitoring system,which includes displacement monitoring of surface and subsurface,crack monitoring,groundwater monitoring and rainfall monitoring,is set up,and new technologies and methods involving GPS and GIS as well as automatic monitoring technologies have been adopted in the system.Hydrogeology and engineering geology conditions are analyzed,and deformations of Xiakou landslide in natural and saturation conditions are simulated by applying FLAC software,which shows deformation characteristics and mechanism of the landslide,and provides the basis for evaluation of the landslide.更多还原
