摘　　要：针对某综合废水处理厂新建废水处理复合生物池池壁,采用无粘结预应力混凝土结构,给出了池壁在水压力、土压力、温度作用下的内力计算方法,根据最不利荷载组合进行配筋计算及施工过程中池壁混凝土应力验算,在池壁预应力筋施工过程中,环向预应力筋应两端张拉,竖向预应力筋一端张拉,且环向预应力筋和竖向预应力筋张拉应对称进行.To increase the capacity of sewage disposal, a new complex biology tank with its wall adopted an unbonded prestress concrete structure was constructed in a sewage treatment plant. The method to calculate the internal force of the wall under water pressure, soil pressure and temperature was investigated. The reinforcement calculation was carried out based on the worst load combination, and the concrete stress of the wall during the construction was calculated as well. Results indicate that the circular prestressing reinforcement should be pulled oppositely, while the vertical prestressing reinforcement should be Pulled to one end, and the pulling of both reinforcements should be performed symmetrically.
