摘要
以长江新城多要素城市地质调查项目为依托,在广泛收集资料和野外调查的基础上,选取深部地球物理场、地震活动、断裂稳定性、现代构造应力场、岩土体结构、地质灾害条件六个指标,采用模糊数学方法将长江新城区域地壳稳定性分为稳定、次稳定、次不稳定和不稳定四个等级。依据区域地壳稳定性评价结果,从构造稳定性、岩土体稳定性和地面稳定性方面为长江新城的规划建设开发提出需要合理开发利用土地资源和注意的环境地质问题等地学建议。
Relying on the multi-factor urban geological survey project of Changjiang New Town,on the basis of extensive collection of information and field investigation,6 factors,including deep geophysical field,seismic activity,fracture stability,modern tectonic stress field,rock and soil structure,and geological disaster conditions are selected as evaluation factors.A fuzzy method is applied to the analysis of the regional crust stability in Changjiang New Town,in which the research region is divided into 4 grades,including stable region,substable region,subunstable region and unstable region.According to the evaluation results of regional crustal stability,geological suggestions are proposed for the planning,construction and development of Changjiang New Town,from the rational development and utilization of land and environmental geology.
