基于监测资料的临江岸坡安全性模糊综合评判

位移、渗压及降雨是岸坡安全性的重要监测项，在考虑位移、渗压及降雨的基础上，结合临江岸坡水位监测信息，分别为其划分模糊评判等级，利用模糊统计和指派函数的方法得到各级指标隶属度矩阵，采用熵权法和层次分析法确定各指标权重，通过隶属矩阵与权重向量进行模糊合成得出评判结果。以长江某岸坡安全性为实例，基于监测信息，实现了该岸坡的综合评判，验证了评判系统的可行性及合理性。

A Fuzzy Comprehensive Evaluation for Safety of River Bank Slope Based on Monitoring Data

Slope displacement, osmotic pressure and rainfall are important monitoring items. In this paper, considering the displacement, osmotic pressure and rainfall and combining with the water level monitoring information of river bank slope, their fuzzy evaluation levels are divided respectively. Index membership degree matrix at all levels is obtained by the method of fuzzy statistics and assigned function; the index weights are determined using the entropy weight method and analytic hierarchy process (AHP); and the evaluation results are obtained by fuzzy synthesis of the membership matrix and weight vector. Take a bank slope in the Yangtze River as an example, the comprehensive evaluation of the bank slope is realized and the feasibility and rationality of the evaluation system is verified based on the monitoring information.
