摘要
Abstract
Taking shield construction on Metro Line 5 in Shenzhen as the engineering background, the construction of the shield tunnel from Honglang Station to Xingdong Station was monitored and measured. Depending on the measured data, the characteristics of soil deformation caused by tunnel construction by means of soil pressure balancing shield is analyzed; and the course of ground surface settlement and its distribution law are studied. Combined with theoretical research and three-dimensional numerical calculation, the comparison between the result of finite element simulation and the measured data is carried out to show the match condition is good.关键词
