近年来,随着经济建设的快速发展,城市地铁交通工程建设不断兴起,由于地铁设计要求的特殊性和城市地质条件的多样性,城市地铁工程勘察具有鲜明的专业特色。本文结合长沙城区特定的地质条件,从构造地质、地震地质、地层结构及岩土特性、水文地质条件等方面对长沙地铁的工程地质问题进行了阐述,对下一步勘察的工作重点和难点问题提供了建议。
In recent years, with the rapid development of economic construction, the construction of urban subway traffic engineering has been on the rise. Due to the particularity of subway design requirements and the diversity of urban geological conditions, urban subway engineering survey has distinct professional characteristics. Based on the specific geological conditions in Changsha urban area, this paper elaborates the engineering geological problems of Changsha Subway from the aspects of tectonic geology, seismic geology, stratigraphic structure, geotechnical properties and hydrogeological conditions, and provides the key and difficult problems for the next survey Suggestion
