中文摘要:京津地区是首都北京和天津所在地,随着区内工程建设规模的日益扩大及经济建设的快速发展,区域地壳稳定与否已成为城市发展的重要制约因素之一。通过对研究区区域地质背景、新构造活动、现今地壳形变、地震、现今构造应力场、岩土体工程地质特征、地质灾害特征以及外动力地质作用等研究分析,利用模糊数学方法,照地壳相对稳定、相对较稳定、相对较不稳定和相对不稳定4个等级,对京津地区地壳稳定性进行了综合评价。 |

The Evaluation of Regional Crustal Stability in Beijing and Tianjin Area |
|
|
Abstract:With the increasingly enlarged project scale and rapid economic development,regional crustal stability has become one of the important factors restricting urban development in Beijing and Tianjin area.Based on a study and analysis of regional geology,neotectonic activity,modern vertical deformation of the crust,earthquake,modern structural stress field,rock and soil geology,geological hazards and outer power geological action by using Fuzzy mathematic method,it is suggested that four relative stable grades should be classified in this region,i.e.,stable,sub-stable,less stable and instable. |
