摘要
城市地铁盾构法施工隧道,盾构机进、出站时常发生涌水涌砂现象,结合北京地铁和天津地铁工程实例,根据盾构工作井的围护结构和工程地质、水文地质条件,通过方案比选,合理地选用预防措施,能起到很好的效果。
In subway shield tunnel construction,there often occured frequent phenomena of water and send gushing when shield into and out,with Beijing and Tianjin metro subways as examples and under shield work well envelope and engineering geological and hydrogeological conditions through the scheme comparison,a reasonable preventive measure can be selected,which will play a very good effect.
