摘要: 为解决复杂地质条件下盾构选型难的问题,通过跟踪深圳地铁12号线怀福区间EPB/TBM双模盾构项目及翠怀区间与福永区间复合盾构项目的施工过程,从掘进参数、施工进度、设备利用率、滚刀磨损、岩渣形态等方面对2种类型盾构在岩石地层中的掘进性能进行对比研究。结果表明: 1)在岩石地层中双模盾构TBM模式下采用中心皮带机出渣,常压空舱推进,刀盘推力和转矩主要用于破碎岩体,刀盘转速高,滚刀磨损慢,岩渣完整性较好; 2)双模盾构EPB模式及复合盾构采用螺旋输土器的出渣效率低,土压舱内渣土堆积,导致刀盘需较高的推力和转矩,以带动土压舱内渣土推进及转动,刀盘转速小,贯入度低,推进速度慢,并且螺旋输土器口喷渣严重,滚刀异常磨损多,清渣及滚刀更换耗时较长,设备利用率低; 3)针对长距离岩石地层,双模盾构TBM模式的施工速度可以达到双模盾构EPB模式的4倍、复合盾构的3~6倍。

Abstract: Shield type selection is critical for tunneling efficiency in complex geological conditions. In the Shenzhen metro line 12, an EPB/TBM dual-mode shield was used in the Huaide-Fuyong section, whereas a composite shield was applied in the Cuigang Industrial Park-Huaide and Yonghe-Fuyong sections. A comparative analysis is performed on the tunneling performance differences between these two shield types in rock strata, focusing on operating parameters, construction progress, machine utilization, cutter wear, and rock muck conditions. The results reveal the following. (1) In rock strata, the dual-mode shield in TBM mode uses a central belt conveyor for mucking and operates with an empty soil chamber under atmospheric pressure. The cutterhead thrust and torque are the primary factors affecting rock-breaking efficiency. This results in a high cutterhead rotation speed, a low disc cutter wear rate, and good rock muck integrity. (2) The screw conveyor on the dual-mode shield in EPB mode and the composite shield results in low mucking efficiency. The soil chamber fills with muck, requiring higher thrust and torque to transport it. As a result, the cutterhead rotation speed and penetration rate are low, and the cutters experience severe wear, leading to low equipment utilization and overall tunneling efficiency. (3) In long-distance rock strata, the advance rate of the dual-mode shield in TBM mode is four times faster than that of the dual-mode shield in EPB mode and three to six times faster than that of the composite shield.
