摘要
针对南京地铁机场线1号风井-禄口机场区间隧道,在长距离高强度岩层兼上软、下硬复合地层中穿越重要建(构)筑物的施工环境下,采用TBM和EPB双模式可转换盾构掘进施工,既能满足在高强度硬岩中掘进效率,又能保证盾构穿越上软、下硬复合地层时建(构)筑物的安全。
In relation to the interval tunnel between the Air Shaft 1 at Nanjing Metro Line for Airport and Lukou Airport, where the important structures pass the long-distance high-strength rock and upper-soft lower- hard complex strata, TBM & EPB dual-mode switchable shield tunneling was used. It can not only meet the tunneling efficiency in the high-strength hard rock, but also ensure the safety of the structures which pass upper-soft lower-hard complex strata.
