摘要
深圳地铁一期工程国老区间南段暗挖隧道为单洞双层隧道,地质条件复杂,富含水砂层距离隧道顶部仅0～2m,采取了多种地面和洞内的止水加固措施,积累和形成了该类地层中暗挖隧道止水加固施工技术的经验。
The coveredexcavation tunnel of the south guolao section of the first stage Shenzhen Subway project is a singletunnel and doublefloors tunnel, geological conditions of this area are very complex, and the distance between waterrich sand stratum and the top of the tunnel is about from 0 to 2 meters. Engineers adopted many waterstop and strengthening measures on ground and in the tunnel, and accumulated experience of waterstop and strengthening construction techniques of coveredexcavation tunnels in similar strata.
