地面沉降危险性分级标准初探

地面沉降是我国广大平原区最主要的地质灾害。各评估单位对其都有详细的研究和论述,但对危险性程度的划分,尚无统一标准。以沉降速率或累计沉降量划分均不全面,难以给建设单位和规划部门提供一个系统的量化的指标。现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,拟对地质灾害评估提供统一的分级标准。

Preliminary Studies on Dangerous Grading Standard of Land- subsidence

Now land - subsidence is the most major geological calamity of the large plain district of our country. Each assessment unit has done a detailed research and exposition for but there no unified dangerous grading stadard,so as subsiding speed or mount to divide the settling amount is not overall,the index is hard to offer systematic quantification for the constructing units or planning departments to make policy scientifically. The paper tries to apply the level analysis law with orthogonal test law for land - subsidence dangerous quantity grading in order to offer an unified dangerous grading standard for the geological calamity assessment.
