摘要
Abstract
Based on the construction case of a box culvert above Foshan Metro Line 3,the deformation law of the underground subway tunnel during different construction periods of the box culvert was analyzed.The research results indicate that the deformation of the underground subway tunnel caused by box culvert construction exhibits different spatial temporal distribution patterns.The tunnel uplift is related to geological losses,the distance between the tunnel and the center-line of the foundation pit,and the depth of tunnel burial.The relationship between tunnel uplift and the distance from the tunnel to the excavation center-line of the box culvert can be represented by the Peck curve function which is considering the effect of soft soil consolidation.关键词
