济南市绕城高速西环段地质灾害特征及危险性研究

Study on the characteristics and risks of geological disasters in the western section of Jinan Ring Expressway

济南市绕城高速西环段地质环境条件复杂,地质灾害主要有崩塌、矿山采空塌陷及伴生地裂缝、地面沉降等。本文根据地质灾害发育类型将项目区分为地质条件稳定区域和可能发生地面沉降、采空塌陷、崩塌、岩溶塌陷的区域,并对其进行建设用地适宜性评价,其中Ⅰ区、Ⅱ-1区、Ⅳ-1区、Ⅴ区建设用地适宜性为适宜;Ⅱ-2区、Ⅳ-2区建设用地适宜性为基本适宜;Ⅲ-1区、Ⅲ-2区建设用地适宜性为适宜性差。

The geological environment conditions of the western section of Jinan Ring Expressway are complicated,with prominent geological disasters such as collapse,mining caving collapse,and associated ground cracks and subsidence.In this paper,According to the development type of geological hazards,the project area was divided into areas with stable geological conditions and areas where ground subsidence,mining collapse,and karst collapse may occur.Among them,zoneⅠ,Zone II-1,Zone IV-1 and ZoneⅤwere considered suitable as construction land.ZonesⅡ-2 andⅣ-2 were considered to have a basic suitability for construction.However,ZonesⅢ-1 andⅢ-2 were considered to have poor suitability for construction purposes.
