Study on Filling Design of Sites near the Existing High-speed Railway Bridge |
| |
| Abstract: | The paper is based on the filling of motor vehicle application site of a high-speed railway bridge in the North China Plain, according to the different filling distance and different packing and using finite element method, the settlement deformation of the bridge of high speed railway resulting from the additional load caused by the filling is calculated. Combining the maintenance requirement of the railway authority with the settlement deformation calculation results, this paper puts forward the reasonable filling space and the requirement of the light packing, which provides reference for the similar projects in the future. |
