- Abstract:
- Application of finite element method in pipe shed-box culvert jacking method is introduced in No.35 water diversion outlet of Puyang supporting water supply projects crossing Daguang Expressway and Puhe Expressway of South-to-North Water Diversion Project. Box culvert jacking calculation was analyzed by using FLAC3D, and stress of box culvert and pipe shed in the construction process and settlement and deformation of highway pavement during the jacking process were simulated to determine a reasonable construction organization design. Under the condition of silt fine sand, a horizontal jet grouting pile was used for reinforcement, so as to solve the safety problem of highway pavement stability. The results aim to provide technical support for water supply of the project on schedule.
