摘要
城市化的快速发展促使城市建设中的地铁隧道和基坑工程规模的不断加大,针对城市建筑密集区域存在的基坑开挖对下方地铁隧道产生的环境岩土问题,结合广州地铁珠江新城站区段,参照既有的计算分析的结果,归纳了防止基坑开挖时下方盾构隧道结构变形过大的措施,可供类似工程参考。
Rapid urbanization process brings development of large-sc.,de foundation pit engineering and subway tunnel in the city. In view of some geoenvironmental problems due to negative impact of foundation excavations on adjacent existing subway tunnels below in congested urban district of large cities,a calculation analysis is given combined with the construction work at Zhujiang New Town station section of Guangzhou metro line 5, the inductive measures to prevent the large structural deformation of shield tunnel due to foundation pit excavation were given, which can provide reference to similar engineering.
