介绍了中国三峡库区蓄水滑坡监测系统的方法。目前，根据滑坡地质分类，确定了监测区域和监测方法，包括监测仪器的种类、仪器的安置和校准精度、仪器安置的适宜周期等。为优化监测系统，完成库面波动影响滑坡位移和地下水位的敏感性分析，确定监测断面和监测点的布置。以三峡水库渐进蓄水产生的石榴树堡滑坡为例，采用三维有限元分析方法对位移行为和地下水位潜在波动进行了模拟。采用模糊集评价法对石榴堡滑坡进行敏感性分析。至此，十六树堡滑坡监测网络初步建立。
A methodology for monitoring system of an impoundment-induced landslide in Three Gorges Reservoir Area, China is introduced. Currently, based on landslide geological classification, the monitoring regions and methods which include types of monitoring instruments, placement and calibration precision of instruments, and appropriate periods for instrumental placement is confirmed. To optimize the monitoring system, sensitivity analysis of displacements and the water table in landslides affected by reservoir surface fluctuation is completed to determine the layout of the monitoring cross sections and the monitoring points. As a case study, the behavior of displacements and the potential fluctuation of the water table in the Shiliushubao landslide, produced by the gradual water impoundment at Three Gorges Reservoir, has been simulated using 3D finite element method analysis. The sensitivity analysis of Shiliushubao landslide is investigated by the fuzzy set evaluation method. As a result, the monitoring network of Shiliushubao landslide is established.
