济南市区地质灾害与环境岩土工程问题的风险度与风险评价

城市地质灾害与环境岩土工程问题是城市地质学研究的重要内容,加强城市地质灾害与环境岩土工程问题研究,对城市可持续发展有重要实际意义。本文在对济南市区地质灾害与环境岩土工程问题研究分析的基础上,制定了济南市区地质灾害与环境岩土工程问题风险评价优势指标和层次结构模型,并采用层次分析法(AHP),确定了各优势指标的权值和重要性排序,最后将研究区划分为若干单元,建立模型,计算出各单元的风险度大小,根据各单元的风险度基准值大小,对济南市区的地质灾害与环境岩土工程问题进行了分区,这对济南市的城市建设与发展有重要指导意义。

DEGREE OF RISK AND RISK EVALUATION OF GEOLOGICAL HAZARDS AND ENVIRONMENTAL GEOTECHNICAL PROBLEMS IN THE DISTRICT OF JINAN CITY

Urban geological hazards and environmental geotechnical problems are an important part of urban geology.It is of practical significance for urban sustainable development to strengthen the study on urban geological hazards and environmental geotechnical problems. Based on the analysis of urban geological hazards and environmental geotechnical problems in the district of Jinan city, priority index and hierarchy structure model of risk evaluation of urban geological hazards and environmental geotechnical problems are established, and an analytic hierarchy process is adopted to determine the weighting factor and priority sequence for each of the priority indices.This is discretized into cells,and a model is established to calculate the degree of risk.Based on the risk values of the cells,the urban geological hazards and environmental geotechnical problems in the district of Jinan city are classified into different regions,to provide guidance for the urban construction and development of Jinan city.
