摘　　要：我国目前阶段以及未来都有大量的桥梁需要进行检测和承载力评估。论文以国内某座预应力混凝土简支空心板梁桥为背景,介绍了基于静载试验的桥梁检测内容、过程和方法。在桥梁结构的试验测试数据和理论计算结果比较分析的基础上,对桥梁的横桥向连接性能、各板的弹性工作状况以及受力状态等方面进行了评价。同时该桥的测定和分析方法也可作为同类桥型设计和施工的参考。There are a number of bridges in China which are needed to be tested and assessed at this stage and also in the future.This paper tells about the content and the process of the inspection based on static load test of one prestressed simply supported plate girder bridge.The cross-bridge connection performance,elasticity work condition of each beam and the stress state of the bridge are evaluated after analysising and comparing the experimental test data and the theoretical calculation result.This bridge＇s method of test and analysis can be reference for the design and construction of the same kind of bridges.
