摘要
结合苏州轨道交通8号线徐阳路站基坑紧邻敏感浅基民房且止水帷幕未隔断基坑内外水力联系的实际情况,通过增加靠近房屋侧地墙插入深度(底部增加素混凝土墙),延长地下水的渗流路径,增强了邻近侧止水帷幕的挡水效果,同时通过不同工况下的降水模拟对民房的影响分析,优化了坑内降压井的布置,减弱降水对民房的不利影响。
Combined with Suzhou rail transit line 8 xuyang road station foundation pit close to sensitive shallow base houses and water curtain,by increasing the depth of the house side wall insertion at the bottom of the groundwater seepage path,enhance the near side water curtain effect,and through the influence of the precipitation simulation of houses,optimize the layout of the antihypertensive well in the pit,reduce the adverse effect of precipitation on houses.
