摘要
以南京地铁6号线下穿高速铁路桥梁为背景,对深埋地铁盾构隧道于岩层中近距离下穿高速铁路桥梁时的施工参数进行了研究。通过对现场施工参数及桥梁变形和地表变形的分析,认为在此种工况下本文涉及到的施工参数值的确定是合理的,可为类似条件下盾构隧道的施工提供参考。
The shield tunnel passing under a bridge high- speed railway on Nanjing metro Line 6 is taken as the back- ground, the construction parameters of deep-buried shield tunnel short-distance traversing the rock stratum are stud- ied. Based on the analysis of construction parameters and observation data of bridge and ground deformation, the construction parameters obtained in these conditions are considered reasonable, they can provide feasible reference for shield tunnel construction under similar circumstances.
