Abstract

With the acceleration of urbanization, urban subway, light rail and other underground transportation projects are in urgent need of expansion and new stations, the demand for rapid construction, cost reduction and quality improvement is gradually increasing, the assembly building just to meet this demand, can quickly build new stations, to meet the needs of the rapid growth of urban transportation. This paper takes Shenzhen Metro Line 13 station as the engineering background to explore a more reasonable temporary steel support arrangement, through MIDAS simulation of the soil layer as well as the overburden of the station after the application of temporary support and structural self-weight load conditions and boundary conditions, for different assembled station entrances and exits of the ring-frame girder and temporary steel support, to analyze different working conditions corresponding to the force mode and displacement mode, and to arrive at the reasonable number of temporary steel supports and temporary steel supports corresponding to the ring-frame girder, as well as the number of ring-frame girder and temporary steel support corresponding to the assembled station. The number of temporary steel supports and the length of ring frame girders for different ring frame girders are analyzed to get the reasonable recommendations for different ring frame girders.
