桂城南区1＃雨水泵站扩建工程沉井结构设计

摘要

Take the 1st pump station expansion project in the south Guicheng as an example , project selection and structural design of the pump station are introduced under the conditions such as high underground water level , nearby complex conditions and soft soil foundation .It can be concluded that open caisson is the best project of the pump station structural design .The structure design of the open caisson especially the calculation of the thickness of the wall , some effective measures of the stability of the caisson ’s sinking are introduced .%以桂城南区1＃雨水泵站扩建工程为例，介绍了在高地下水位、周边环境复杂、软弱土质条件下，泵站结构的选型与分析。结果表明，采用沉井是泵站结构施工的最优方案。对沉井的结构设计特别是井壁厚度的确定进行了详细的介绍，并给出了确保沉井下沉稳定的相关措施。
