| 摘 要： | 在三峡水库蓄水和运行条件下,三峡库区水库型滑坡不同部位的地下水位和位移的改变表现出对库水位变化的敏感程度不同的特征.根据位移的变化对库水变化敏感程度的不同与监测信息量获取大小的关系,采用模糊模式识别方法对三峡库区水库型滑坡位移场变化对水库水位变化的敏感程度进行数值分区.借助水库型滑坡位移场变化敏感程度数值分区规律,提出三峡库区水库型滑坡变形监测剖面选取的一般原则.根据该原则,以三峡库区水库型滑坡——泄滩滑坡为工程实例,给出泄滩滑坡变形监测剖面的具体布置.

| Abstract: | Under the conditions of water-impoundment and running of Three Gorges Reservoir,the sensitive degree of the change of displacement to the fluctuation of water level is different in different parts of landslides induced by the fluctuation of water level.According to the relationship between different sensitive degree of monitoring displacement and quantity of monitoring information,the sensitive zones of displacement to the fluctuation of reservoir water level are divided into different degrees by the approach of fuzzy pattern recognition.By means of the numerical subarea regulation of the change of displacement of Xietan landslide,the general rules of the selection of deformation monitoring profiles are put forward.According to the rules,Xietan landslide is a case of landslides induced by the fluctuation of water level of Three Gorges Reservoir, the layout of its deformation monitoring profiles are given. |
