摘要
单梁静载试验是确保桥梁在正常运营后能够安全使用的重要途径,它是检验单梁的结构性能是否达到设计文件和规范要求的一种重要手段。结合某预应力混凝土简支变连续小箱梁桥,介绍了单梁静载试验理论计算分析、检测内容、试验步骤和试验结果分析,通过总结单梁静载试验结果,对该预应力混凝土简支变连续小箱梁桥做出了正确的质量评估,为类似的工程实际提供了参考依据。
The static load test for single girder is an important way to ensure the safety use of bridge after normal operation, which is an important means to inspect whether the structural performance of single girder can meet the requirements of design document and standard or not. In combination with a prestressed concrete simple support - continuous small box girder bridge, the theoretical calculation analysis, inspection content, test procedure and test result analysis of static load test for single girder are introduced. The correct quality evaluation is made for the prestressed concrete simple support - continuous small box girder bridge by summarizing the result of static load test for single girder, so as to provide reference basis for similar engineering practice.
