桥梁荷载试验是直接了解在役桥梁结构实际工作状态，评价其在设计使用荷载下工作性能的有效方法。结合某预应力简支空心板桥，介绍了相关检测内容和检测方法，通过静载试验获得各工况下该桥控制截面的挠度与应变值，并研究其荷载横向分布规律和残余变位等重要指标，以综合评估其承载能力和工作状态。理论研究和试验结果对比分析可知，该桥各片板梁的横向联系良好，无单板受力现象，且残余变位在规范容许范围内，结构处于弹性工作阶段。本文的研究方法可供工程设计参考。

Bridge load test is treated as a direct method to grasp the actual working state of bridge structure to evaluate its performance under design load.Based on a simple supported pre-stressed concrete hollow slab bridge,the paper intro-duced some relevant contents and methods of inspection,and got the actual deflection and strain of each control section through static load test.Furthermore,it investigated the transverse distribution and service state for the purpose of evalua-ting the carrying capacity and working state comprehensively.Compared theoretical analysis with the actual experiment, each veneer connects closely in horizontal,which indicated that no veneer works separately.Besides,residual displacements were within the specified range,therefore,the bridge belonged to elastic stage.The research methods of the paper can be a reference for engineering design.
