| Abstract: | The bridge is located in soft soil area, under-crossing multi-tracks railway. With the method of pipe jacking construction and the technology of manual dig-pouting pile, overhead steel beams are used for protection. The design of working pit ensures the security of foundation pit in stability and lateral displacement, and other respects, utilizing the combination of jet grouting pile and filling pile to guard the foundation pit. The design of the bridge provides a reference for similar projects. |
