地铁车站止水帷幕对南京秦淮河古河道地下水流场的影响分析
Analysis on influence of subway station waterproof curtain on groundwater flow field of Qinhuai ancient channel
摘要
Abstract
Taking one subway station of the Line 1 of Nanjing subway as an example, the groundw-ater seepage field features are analyzed under different conditions:before and after the setting of wa-terproof curtain;different setting depth of the curtain in the aquifer. The results show that the water-proof curtain has serious barrier effects on the groundwater flow field of the ancient Qinhuai River channel. The longitudinal impact distance reaches more than 200 m before and after the curtain. A certain degree of groundwater head difference will be caused before and after the curtain, which in-duces the additional settlement of soil, the unsymmetrical load on underground structures or other en-gineering problems. The groundwater flow fields are different when the setting depths of curtain are not identical. The influence will increase significantly when the setting depth becomes larger.关键词
