地面沉降危险性分级量化分析

地面沉降是我国部分平原区最主要的地质灾害。有关评估单位对我国主要城市地区的地面沉降灾害都有详细的研究和论述,但在有关其地质灾害危险性程度划分,尚无统一标准。难以给建设单位和规划部门提供系统的量化的指标,用作科学决策。本文尝试应用层次分析法和正交试验法对地面沉降危险性程度进行量化分级,为地质灾害评估提供统一的分级标准。

Quantitative Analysis of the Danger Levels of Ground Subsidence

Ground subsidence is the major geological hazard in most plain areas of China.The relevant assessment units have made detailed researches and expositions for it,but there lacks a unified standard for its danger levels.Therefore,it is hard to provide a systematic and quantitative index for the construction units and planning departments to make scientific decisions.This paper attempts to offer a unified grading standard for assessment of geological hazards by using the hierarchical analysis and orthogonal test methods to grade the danger levels of ground subsidence.
