摘要
在地铁建设前应进行岩土工程勘察,其中工程地质分析与评价是重要的环节.本文以广州地铁某线路的琶洲站～埔南路站区段为例,进行了工程地质分析与评价.该地铁段设计全长20.36 km,涉及3个车站和4个区间,工程地质条件、水文地质条件及周边环境复杂.通过对该区段的工程地质分区、地表水、地下水、不良地质作用和地质灾害、特殊性岩土进行综合分析与评价,得出了场地基本稳定、工程建设较适宜的结论,为地铁工程的规划建设提供了地质依据.
Abstract
Geotechnical investigation should be carried out before the subway construction,in which the engineering geological analysis and evaluation is an important link.Taking the Pazhou Station to Punan Road Station section of a certain line of Guangzhou Metro as an example,the engineering geological analysis and evaluation are carried out The design length of this subway section is 20.36km,involving 3 stations and 4 sections.The engineering geological conditions,hydrogeological conditions,and surrounding environment are complex.Through comprehensive analysis and evaluation of the engineering geological zoning,surface water,groundwater,adverse geological actions,geological disaster,and special rock and soil in this section,the conclusion was drawn that the site is basically stable and the engineering construction is suitable,providing a geological basis for the planning and construction of subway projects.
