某车站预应力结构设计施工及监测

Design, construction and monitor of prestressed structure on certain bus station

为了说明现代钢筋混凝土预应力技术以及先进监测手段在解决大难度工程问题中的应用,通过合理运用广义预应力技术和预应力度概念,对结构布置、设计、施工和控制的方法及其应用进行了探讨,同时对不需验算裂缝宽度的预应力结构设计方法进行了分析.解决了某工程的大跨悬挑结构中的难题,得出一些有用的结论,对同类工程有一定的参考意义.

Aimed at illuminating the application of prestressed concrete technology and modern monitor method to solving difficult problem met in project, the generalized prestressed technique and the load ratio for prestressing were utilized reasonably. The method and application were researched in the structural layout, design, construction and control. Meanwhile, the approach for designing prestressed structure without check of cracks width was proposed and analyzed. Solving the problem of actual example with large cantilevers, and it is important to resembling projects.
