- Abstract:
- In design and construction of urban underground utility tunnel, it often encounters the working condition of crossing urban river. Different solutions should be adopted for different projects, including measures such as crossing over a river, under crossing a river and combining existing bridge structures. Taking an urban utility tunnel project as an example, we compared three schemes of the utility tunnel crossing the river. After analysis and demonstration, the scheme of “under crossing the river” was finally determined. The anti-floating design of the structure, anti-scouring design, cofferdam construction and foundation support scheme were introduced in detail. At present, the project has been successfully completed and the operation is good.
