开发构建区域滑坡稳定性智能评价系统,从而对滑坡灾害风险进行有效地评价管理,是一项极具理论价值和现实意义的研究课题。基于Matlab图形用户界面开发环境GUIDE,将模糊综合评判作为评价系统主算法,将岩石强度、岩体完整性系数、地下水、降水量、边坡角、爆破震动、风化蚀变和人为活动等因素作为评判参数并分别赋权重,以高斯型函数和S形函数为各参数的隶属度函数,开发了区域滑坡稳定性的GUI评价系统。以王家坪滑坡工程为例进行了评价演示,结果表明,该系统能实现对王家坪滑坡稳定性的多因素综合评判计算,划定滑坡灾害危险性等级。该系统为区域滑坡工程分析评价提供了一个新的计算处理工具。
It is a very theoretical and practical research subject to develop and construct an intelligent evaluation system of landslide stability so as to evaluate and manage the landslide disaster risk effectively. Based on Matlab graphical user interface development environment GUIDE, the fuzzy comprehensive evaluation is taken as the main algorithm of the evaluation system. Factors such as rock strength, rock mass integrity coefficient, groundwater, precipitation, slope angle, blasting vibration, weathering alteration and human activities are taken as Judging the parameters and assigning weights respectively, the GUI evaluation system of regional landslide stability was developed by using Gaussian function and S-shaped function as membership functions of each parameter. The Wangjiaping Landslide Project was taken as an example to evaluate the demonstration. The results show that the system can realize the comprehensive evaluation and calculation of the stability of the Wangjiaping landslide, and delineate the landslide hazard grade. The system provides a new calculation and processing tool for the analysis and evaluation of regional landslide engineering.
