Abstract:

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.

Key words: landslides, monitoring point, optimal placement, profile, numerical simulation, pattern recognition, sensitivity
