摘要
针对某地铁站基坑围护方案进行优化设计,采用水泥灌浆帷幕,将防渗帷幕底深入到相对不透水基岩中,解决了花岗岩残积土和承压水地区的深大基坑围护问题,检测结果表明施工质量良好,达到了设计要求。
For a program to optimize the design of station foundation pit,and the use of cement grout curtain,the curtain will be impervious to the end of a relatively impermeable bedrock depth to address the granite residual soil water and artesian water of the deep foundation pit area issues.The test results show that the construction of good quality,meets the design requirements.
