| Abstract: | Combined with Yinxing Road Widening Reconstruction Project of Gaogang District, Taizhou, this paper has presented the key technical problems existing in the application of the U-shape structure in the expressway underground passage, such as the structure design, waterproof and anti-floating design, temporary excavation support design, etc. Practice has proved that application of the U-shape structure in the expressway underground passage has the characteristics such low cost, good effect, etc. At present the project has been put into service and operates in good condition. Reference is provided for design and construction of urban underpass expressway widening and reconstruction project. |
