Using the Experiences of Prestressed Concrete on the Erection of Inverted Taper Shaped Water Tower and Cistern 运用预应力张拉施工工艺原理提升倒锥形水塔水箱
With the increasing of long span prestressed concrete bridge adopting cantilever erection construction method, more and more attention are paid to the correlative geometry control theory and practice of long span continuous box girder. 随着采用悬臂拼装施工的大跨度预应力混凝土梁桥的不断增多,与其相关的大跨度连续箱梁悬臂拼装施工线形控制理论和实践日益受到关注。
The offshore approach spans of Hangzhou Bay Sea-Crossing Bridge are all designed to use the 70-m span prestressed concrete box girders that are first simply supported and then made continuous during erection. 杭州湾跨海大桥海上引桥全部采用70m先简支后连续的预应力混凝土箱梁。
