预应力技术在高寨洲小桥施工中的应用

The Application of Prestressed Technology in the Construction of Gaozhaizhou Small Bridge

为增加结构承载力和稳定性、节约材料和降低成本,有必要系统性研究预应力技术在公路桥梁施工中的应用。将预应力技术作为研究对象,整理基本概念,结合具体项目,从钢筋混凝土箱涵设计、钢绞线施工、孔道压浆、定位预应力筋等四个维度,详细分析预应力技术在公路桥梁施工中的操作。

It is necessary to systematically study the application of prestressed technology in highway bridge construction in order to increase structural bearing capacity and stability,save materials,and reduce costs.This article takes prestressed technology as the research object,organizes basic concepts,and combines specific projects to analyze in detail the practice of prestressed technology in highway bridge construction from four dimensions:reinforced concrete box culvert design,steel strand construction,hole grouting,and positioning prestressed reinforcement.
