以深圳地铁11号线为例，对全线30个工点627个地下水水质分析样本进行了统计，得到了整条线路下地下水腐蚀强弱分布状态，并结合线路通过区的填海和海水侵入背景进行了分析，得到了一些结论，为滨海城市海水入侵区地铁线路地下水腐蚀性评价提供了依据。%Taking the Shenzhen metro Line 11 for example,this paper made statistics to 627 groundwater quality analysis samples whole line more than 30 worksites,gained the groundwater corrosion intensity distribution situation of whole line,and combining with the reclamation and seawater intrusive background of line through area made analysis,and obtained some conclusions,provided basis for metro line groundwater corrosion eval-uation of coastal urban seawater intrusion district.
