Based on the engineering background of a subway double-line shield under-passing the frame bridge of Beijing-Guangzhou Railway,this paper studies the maximum deformation,inclination and deformation difference between adjacent frame structures of the four-hole railway frame bridge through on-site monitoring data and numerical simulation,and analyzes the causes of the deformation trend.The results show that the overall deformation of the frame bridge is not only related to the ground loss and the disturbance of shield excavation and grouting reinforcement,but also related to the inclined deforma...
