| 摘 要： | 深圳地铁2号线东延段安托山站—侨香站区间隧道顺利通过富水砂质地层的工程实例表明,在复杂地层中采用地面降水、超前预注浆及水平旋喷桩加固等辅助措施是成功的,也是必要的;另外,在隧道下穿次高压燃气管施工中,采用悬吊保护措施也为矿山法隧道施工和管线的绝对安全带来了技术保障。

| Abstract: | The Antuoshan and Qiaoxiang Stations of the Shenzhen Metro line 2,which pass through water-rich sandy stratum,demonstrate the successful implementation of the auxiliary measures of ground dewatering,advance grouting,and jet grouting.Additionally the measures of hanging protection were adopted during tunnel construction under gas lines with intermediate pressure,ensuring the construction safety of the drill and blast tunnel and the gas lines. |
