区域地壳稳定性评价研究进展与问题，兼谈规范编制

Development and Problems of Regional Crustal Stability Assessment Study Companying with Discussion of the Specification Compilation

区域地壳稳定性评价是工程地质重要的分支学科，是在我国几十年的工程地质实践中发展起来的一项特有的区域工程地质理论方法体系，在重大工程场地选址、国土资源规划、减灾防灾等地质工作中发挥了积极的作用，已经形成了一套较完善的理论方法，被广大工程地质工作者所广泛接受使用。本文通过对区域地壳稳定性研究的回顾和总结，划分了理论发展的四个阶段：上世纪50～70年代的孕育期、60～80年代的形成期、80年代-2l世纪初的发展期、21世纪以来的徘徊期，并分析了目前区域地壳稳定性研究存在的主要问题。在此基础上，结合中国地质调查局第一部区域地壳稳定性调查评价规范的制定，对规范的社会需求、编制理念、主要内容结构等进行了说明，对存在较大争议的问题进行了探讨并给出解决意见，目的为这项我国特有的区域工程地质理论的发展和规范的贯彻实施助一臂之力。

Regional crustal stability assessment, an important sub-discipline of engineering geology, is a unique regional engineering geological theory developed in decades practice of Chinese engineering geological. It played a positive role in engineering site selection, land and resources planning, disaster prevention and other geological work, having formed a better theory, be widely accepted by the majority of engineering geologists. Based on review and summary of regional crustal stability studies, this article divided its development experiences to d stages： ① incubation period of 1950s - 1970s; ② established period of 1960s - 1980s; ③ development period from the 1980s to the early 21st century; ④ wandering period from start of 21st century to the present, and analyzed the main problems of the regional crustal stability studies. On this basis, combined with the compilation of first specification of Investigation and Assessment for Active Fault and Regional Crustal Stability by China Geological Survey Bureau, this paper described the social needs, guideline and main content structure of the specification, discussed some problems of considerable controversy and given corresponding solutions. The aim of those work is to contribute a help to the development of the specific engineering geological theory and the implement of this specification.
