| 摘 要： | 城市轨道交通工程下穿重要交通要道、建(构)筑物是不可避免的,工程自身和周边建(构)筑的安全控制非常困难.文章结合广州地铁六号线黄花岗站至沙河顶站暗挖区间下穿市内环路段工程所遇到的隧道超浅埋、围岩稳定性差、周边建(构)筑物保护难等问题进行了分析,通过采用钢便桥、WSS全断面注浆、大管棚、CD工法等措施,有效解决了超浅埋隧道施工及周边建筑保护中的相关问题.

| Abstract: | While it is very common for urban rail transit projects to be constructed beneath important traffic arteries,it is very difficult to guarantee the safety of these projects and the buildings surrounding them.This paper analyzes the bored section of the Huanghuagang Station-Shaheding Station of the Guangzhou Metro Line 6,constructed under an inner ring road,which exhibited such problems as shallow overburden,poor stability of surrounding rocks and the safety risks to nearby buildings.Measures adopted to succe... |
