预应力摩阻损失分析及对施工的指导意义

Analysis of the Prestressed Friction Loss and the Guiding Significance to the Construction

在预应力混凝土桥梁施工中,因为预应力摩阻损失的影响,桥梁的实际预应力小于或大于设计预应力值时,都将使桥梁留下安全隐患。文章对预应力桥梁的预应力摩阻损失影响因素做了简要的分析。

During the construction of prestressed concrete bri-dge, because of the influence of prestressed friction loss, which wil make the bridge safety hidden trouble when the actual prestressed of bridge is less than or greater than the design of prestressed value. This article carries on the brief analysis of t-he prestressed friction loss factors of the prestressed bridge.
