| 摘 要： | 通过对西安市区域地壳稳定性与地质灾害评价和研究所取得的地质、物探、测量、模拟实验等方面的成果资料的分析,综合考虑内、外动力地质作用及介质条件等因素,选择了6种影响西安市区域地壳稳定性的主要因素作为稳定性评价的指标体系,运用模糊数学方法进行了该区的区域地壳稳定性评价与分区,将西安市地壳稳定性划分为次较不稳定、较不稳定和不稳定三级共10个区域。在此基础上,对西安市城市建设与发展规划提出了指导性的建议。

| Abstract: | The authors carried out the evaluation and study of the regional crustal stability and geological hazards in Xi'an City. A wealth of data was gained in geology, geophysical prospecting, surveying and model experiments. According to an analysis of these data and considering such factors as the endogenic and exogenic dynamic geological processes and medium conditions, six principal factors affecting the crustal stability in Xi'an City are selected as a system of the stability evaluation indicators and the fuzzy mathematic method is applied to make a regional crustal stability evaluation. The authors divide the crustal stability in Xi'an City into three grades, sub-unstable, relatively unstable and unstable, and ten areas. On that basis, some guidance suggestions for the urban construction and development plan in Xi'an City are put forward in this paper. |
