本文概述了预应力混凝土蛋形消化池在我国的开发和应用情况。实践表明 ,采用无粘结预应力张拉工艺比采用有粘结预应力张拉工艺具有明显的优越性 ,环锚是蛋形消化池环向张拉配套用的首选锚具 This paper summarizes the development and application of prestressed concrete egg-shaped digester in our country. Practice shows that the use of unbonded prestressed tensioning process than the use of bonded prestressed tensioning process has obvious advantages, the ring anchor is egg-shaped digestive loop supporting the use of the preferred anchor
