摘　　要：本文结合工程实例论述了215m超长生化池结构的设计方法,取消了温度伸缩缝,避免了传统伸缩缝采用橡胶止水带漏水、老化给生产管理带来的麻烦,提出了采用预应力混凝土结构进行设计与施工的思路,该方法的采用大大加快了施工进度,增强了结构的耐久性和抗震性。Combining with an engineering project,the article discussed different design methods of 215 m long large concrete aeration tank.The monolithically post-tensioned concrete tank without any expansion joints can avoid the water leakage and rubber waterstop perished.Prestressed concrete design and construction was pointed out.The monolithically technique can accelerate the tank construction speed and improve the durability and seismic performance of the structure.
