摘要
根据兰州地区湿陷性黄土分布状况、湿陷特征及其引发的湿陷性地质灾害发生频率和对此造成的毁坏情况,以Fuzzy数学理论分析了形成黄土湿陷灾害的主要因子和权重,以此确定黄土灾害的危险性级别和等级,从而实现对黄土湿陷灾害的预防和有效治理.
According to the collapsible loess distribution of Lanzhou region features of loess and the triggered collapsibility of geologic hazards, the frequency and damage caused by this situation, fuzzy mathematical theory is used to analyze the main factors and weights of the loess collapsible disasters so as to determine the grades and levels of loess disasters and, to realize the loess collapsible disaster prevention and effective regulation.
