Influence Analysis on Lateral Mechanical Characteristics of Adjacent Bridge Pile Foundation under Railway Load |
| |
| Abstract: | A certain railway traverses the Southern Sichuan Intercity Railway under the Shaping Town Bridge in the form of a roadbed. The two railways were constructed in the crossing area at the same time. In order to eliminate the additional horizontal stress effect of the roadbed railway on the bridge type railway from the design source, based on the finite element software, in the construction and operation stages, the additional horizontal stress of the bridge pile foundation was studied. And compared with the theoretical calculation results, it was found that the influence of the railway load on the pile foundation under the same cap was different. The redistribution of stress is closely related to the position of the load and the terrain fluctuations, and its research results have certain reference value for the analysis of similar problems. |
