U型槽式结构在高速公路下穿通道中的设计与应用

结合泰州市高港区银杏路拓宽改造工程,介绍了U型槽式结构在高速公路下穿通道中应用的结构设计、防水抗渗抗浮设计以及临时开挖支护设计等关键技术问题。实践证明,U型槽式结构在高速公路下穿通道中应用的优点有成本低、效果好等特点,目前己竣工通车,使用状况良好。可供城市高速公路下穿通道拓宽改造工程设计、施工参考。

Design and Application of U-shape Structure in Underground Passage of Underpass Expressway

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.
