【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。更多还原

【Abstract】 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 pre- stressing 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.更多还原
