摘要
针对广州地铁二号线南延段东晓南站两端小间距盾构隧道区间,以盾构管片变形和受力及地表沉降作为主要控制目标,对搅拌桩加固施工方案和中隔墙素混凝土钻孔桩方案进行了数值模拟分析和投资比较,为此工程的顺利实施提供依据和指导,可供类似工程参考。
Aimed at Guangzhou metro shielded tunneling with small interval, cement mixing method and mid-board concrete drilling stake construction projects are numerical simulation analyzed and invest compared based on shield tube distortion and land subsidence. The basis and guidance are supplied for real engineering and some meaningful conclusions are got ten as the reference for similar engineering.
