摘要
Abstract
By the roads and existing buildings of surrounding cities,the construction of underground tunneling space is limited.The rationality of the layout of the supporting structure will influence its slag efficiency,so the rational layout of the supporting structure will have a significant effect on the construction of the tunnel.According to the method of field measurement and numerical simulation,the surrounding ground subsidence caused by shaft excavation,the horizontal deformation of the borehole wall and the deformation of the borehole wall were carried out based on the excavation of a metro tunnel in Qingdao.The effective area ratio is used as the evaluation index of the shaft deformation control effect and the rationality of the spatial arrangement,and the difference between the two kinds of support forms was analyzed.The results showed that with the effective area ratio of the hole unchanged,the control effect of the ring beam is better than that of the bracing,and the rationality of the deformation and the layout of the shaft is taken into account.关键词
