摘　　要：预应力的施工将是整个LNG低温储罐外罐施工的关键,对储罐的安全使用将起到最直接的作用,并影响到外罐的外观质量。现浇后张法有粘结预应力混凝土结构是目前国内LNG低温储罐的主要结构型式。预应力施工的关键工序有:预埋管道、穿筋、张拉、灌浆等。本工文过杭州市东部LNG应急气源站工程实践总结而成。Construction of prestressed LNG will be the key to the construction of the outer tank cryogenic tank, Safe use of the tanks will play a role in the most direct and affect the quality of the outer appearance of the tank.After the cast tensioned bonded prestressed concrete structure is currently the main structural type LNG cryogenic storage tanks.Construction of Prestressed key processes are ： embedded pipes, wear bars, tensioning, grouting.The paper work through the emergency gas source in Hangzhou in eastem LNG station project summary practice together.
