典型滑坡监测点优化布置

利用数值模拟技术与模糊模式识别算法提出了滑坡监测点优化布置的基本方法。以链子崖危岩体为例，以Ⅳ-Ⅳ′剖面作为滑坡监测点优化布置的典型剖面，根据监测变量（位移）对外界干扰因素作用下的灵敏度大小与监测信息量获取大小之间的关系，对该危岩体的监测变量（位移）进行了灵敏度分区研究，进而对该典型剖面的监测点进行了优化设计。研究结果表明，链子崖危岩体地表位移监测点宜布置在位移量明显和状态变化灵敏度较高的部位，深部位移监测钻孔宜穿越所有水平位移变化的灵敏区域。

Optimal Placement of Monitoring Points at Typical Landslide

The basic method for optimal placement of monitoring points was established by using numerical simulation technology and fuzzy pattern recognition algorithm. Taking Lianziya dangerous rock body as an example and Ⅳ-Ⅳ’ profile as the optimal object, the sensitivity partition was studied based on the relationship between the sensitivity of monitoring variable (displacement) and the external interference factors and the amount of monitoring information. Then the optimal placement of monitoring points of this profile was designed. The results showed that it was better to locate the monitoring points at these places with an obvious displacement and a relatively high sensitivity, and install the deep displacement monitoring drilling through all the horizon-displacement-sensitivity area.
