大跨度预应力混凝土箱梁静载试验研究

Experimental Study of Large Span Prestressed Concrete Box Girder

静载试验对于掌握桥梁结构的工作性能,判断桥梁结构实际承载能力及有无安全隐患有着重要意义。鉴于此,结合连续箱梁桥实例,介绍静载试验在该桥梁箱梁试验过程中的技术要领,对试验结果进行分析,并对桥梁整体性能和结构安全做出评价,可为类似桥梁静载试验提供参考与借鉴。

The static load test has important significance for mastering the working properties of oridge structure, and judging its actual bearing capacity and potential safety hazard. Given this, taking one continuous box girder bridge as an example, the technical essentials of static load test in the bridge box beam test is intro- duced. The test results are fully analyzed, and an evaluation on the overall performance and structural safety of bridge is made. It can provide reference for static load test of similar bridge.
