摘　　要：湖北宜昌卵形消化池为双向无粘结预应力混凝土结构。为了解预应力张拉及闭水试验过程中池体应力分布的情况,进行了实测工作。通过实测结果和有限元计算分析结果的对比,验证了设计理论并检验出池体在满水荷载作用下的工作性能。The egg-shaped sludge digester in Yichang Hubei Province is a bi-direction prestressed concrete structure. To study the stress distribution, the site measurement of concrete stress of the cell body was carried out during prestressing and watering test. The test results are contrasted with the calculation results using finite element software to verify the calculation method and evaluate the service condition of the digester.
