摘要
钢板桩围堰水下施工具有危险性。为了确保钢板桩围堰施工安全,以天津海河特大桥R#38墩基础的钢板桩围堰为工程实例,采用有限元软件ANSYS建立钢板桩围堰空间有限元模型,考虑了4种工况,进行了有限元施工分析。计算结果表明:R#38墩基础的钢板桩围堰的强度和变形满足要求,可以按设计安全施工。本文可为同类钢板桩围堰的安全施工分析提供参考。
The construction of steel sheet pile cofferdam is dangerous under water. In order to ensure the safety of construction of steel sheet pile cofferdam, based on the case of the steel sheet pile cofferdam of No. R38 pier of Haihe River Bridge in Tianjin, a three-dimensional model for steel sheet pile cofferdam is established by use of the general finite element software ANSYS. Meanwhile, the construction process is analyzed in consideration of four load cases. The results show that the structural design of the steel sheet pile cofferdam of No. R38 pier meets the strength and deformation requirements, and it can be constructed safely according to the design. This work may provide reference for construction of the similar cofferdam.
