- W4317532709 abstract "Infrastructure such as high-speed railways and expressways is in the peak period of construction, and the construction corridor space is limited. There are problems of too narrow spacing and interaction between high-speed railway and expressway. Given the impact of the construction of a high-speed railway expansion station building on the operation safety of the existing expressway, this paper selects the station building pile foundation close to the highway subgrade and the yard frame pier pile foundation close to the station building in the East as the research objects. It uses the numerical simulation analysis method for modeling and analysis; constructs the rock, soil, and support structure model; and simulates the construction process. The deformation laws of the support structure, slope rock, soil mass, and existing expressway subgrade during construction are obtained. During the construction process, due to the excavation and unloading of pile foundation soil mass, the subgrade slope soil mass generally deforms toward the slope toe, which has a certain impact on the highway structure. The maximum settlement of subgrade obtained from the calculation results of the project meets the control standard. It provides a theoretical guarantee for the operation safety of the existing expressway and the safety of the subgrade slope in the process of railway construction." @default.
