摘要
新建桥梁在通车前的验收过程中做检测非常必要,通过检测可了解桥梁结构状态和评定运管荷载等级,确保桥梁使用的安全性和耐久性。以云南某新建预应力混凝土箱梁桥为例,阐述静载试验方案设计,总结分析桥梁检测结果的方法,并与有限元理论计算结果进行对比,结果表明桥梁的使用性能良好,承载能力满足有关规范要求。
Bridge testing is necessary before the opening to traffic. Not only for completion acceptance and management, but also evaluate bridge＇s carrying capacity as well as using capability. In this paper, a method base on loading test and FEM numerical simulation combine is used to test bridge working state. The result show that the project could meet the requirement of the relative criteria.
