［摘要］基于数值模拟技术针对圆柱形消化池常见的五种工况进行了受力分析，并对计算结果进行了对比。研究结果表明，施加预应力后，池壁整个截面在各种工况下皆处于环向受压状态，可以保证结构防渗防漏的设计要求；并且通过五种工况的对比分析还可得，静水压力及壁面温差是结构设计中的控制荷载。所得结论可为相关设计人员提供参考。

Abstract: Numerical analysis was carried out, based on the numerical simulation technology for cylindrical digester with five kinds of load cases, and the calculated results were compared. The research results were shown that after prestressing force was applied, the vertical side wall of cylindrical digester was in the condition of fully compression, which was to ensure the structure of anti-seepage and leak-proof requirement. And through the comparative analysis results of five kinds load cases, temperature and hydrostatic were the controlled loads in the phase of structural designing phase. The conclusion can be a reference for related design workers.
