System for Construction of a Railway Underpass

Deformation Analysis of the Cable Reinforcement System of Large Section Box Culvert Roof Entry and Downward Penetration

“…Jia Peng [20] used the three-dimensional numerical simulation method to analyze and compare the changes of key parameters such as surface settlement and internal forces of the structural system during the construction of the underpass expressway from the perspective of the transformation of the structural system in the whole excavation process and the spatial effect of the construction process. Ramirez Chasco [21] and Wang H [22] et al conducted case studies of the railway and expressway under the box culvert, analyzed the reasons for the large deformation and proposed control measures. This paper takes the project of a Beijing-Harbin railway node under a city road in Beijing as an example, briefly introduces the construction process of key nodes of the large-section box culvert, small box culvert and pipe jacking project at the same time through the railway jacking construction, and analyzes the settlement law according to the measured data, and verifies the feasibility of deformation control measures.…”
