基于荷载试验的预应力混凝土T型梁桥承载能力分析

The Bearing Capacity Analysis of Pre-stressed Concrete T-shape Beam Bridge Based on Load Test

新建桥梁和进行了加固或改建后的桥梁,可通过荷载试验来检验桥梁结构的使用状态和承载能力是否符合设计要求。文中以衢州某新建预应力混凝土T型梁桥为例,介绍了该桥竣工前荷载试验的方案及过程,将实测试验数据与理论计算结果加以对比分析,对桥梁的实际承载能力作出评价,为类似项目交竣工验收提供技术依据。

New bridges and reinforced or reconstructed bridges can be tested by load tests to see whether the use state and carrying capacity of bridge structures meet the design requirements.Taking a newly-built prestressed concrete T-beam bridge in Quzhou as an example,this paper introduces the scheme and process of load test before completion of the bridge,compares and analyzes the actual test data with the theoretical calculation results,evaluates the actual bearing capacity of the bridge,and provides technical basis for the acceptance of similar projects.
