Abstract
Combining with an engineering case,this paper analyzed the measured data of ground surface settlement caused by the super-diameter slurry shield subway tunnel construction.The general rule of the ground displacement happened above the center axis of the subway tunnel during the shield advance as well as the settlement patterns of ground transverse section caused by ground layer loss were obtained.Through fitting Peck formula with the measured data of transverse settlement groove,the general ranges of the characteristic parameters such as width factor of settlement tank and ground layer loss ratio.Advices were given after analyzing the impacts of stop working during the advance of the tunneling shield on ground surface settlement.The findings in this study may provide a good reference to urban super-diameter slurry shield projects.关键词
