| Abstract: | Based on the dynamic monitoring project of one underpass in Dalian,this paper tries to validate the control effect of the ground settlement on the stability of tunnel surrounding rocks during construction of underground passage under urban arterial road by means of analyzing the horizontal and vertical ground settlement curves,convergence curves of tunnel inner perimeter,vault displacement curves.With the numerical calculation tool of the software FLAC,this paper also analyzes the construction of XS-2 # cross-section which was in the south side of the whole construction section at different stages by adopting the plane-strain model.Therefore,we can get the influence curves of ground settlement under different construction stages with considering the release of stress.The result is basically consistent with the field measurements,which has a great significance for the subsequent design and construction of underground projects with similar geological conditions. |
