摘要
针对施工中预应力混凝土桥梁结构的内力、变形控制,总结了桥梁预应力施工控制要点,详细介绍了预应力筋梳束、编束和穿束技术应用以及预应力张拉施工控制,描述了有效预应力检测方法与补救措施。
The main points of construction control of bridge prestress are summarized according to internal force and deformation control of prestressed concrete bridge structure during construction. The application of combing beam, bundle and crossing techniques of prestressing tendon as well as the construction control of prestressed tension are introduced in detail. The effective prestress detection methods and remedial measures are described.
