    Abstract
  • Existing box culverts in important water supply projects are more sensitive to the surrounding construction deformation. For the newly built combined retaining structure of pile and retaining wall around the existing box culverts, it is proposed to analyze the forces and deformation of the retaining structure itself by using "integral rigid frame model" and "support excavation model". Combined with specific projects, the safety analysis of the existing water supply box culvert in the entire process of the construction and operation of the project is conducted through a numerical model. Results verified by numerical analysis and field measurement can provide a reference for similar projects.
