Abstract: Pipe culvert with corrugated steel plate connected by high strength bolt in site, is a new type structure technique. Several corrugated steel plate structures have been installed in north part of highway A30. After several years using, they are working well, and have many advantages comparing with ordinary RC culverts. They can adapt the deformation of settlement of bank on soft soil, can decrease the different settlement between abutment and bank, and can improve the suitability and safety of driving.
