某多跨PC连续梁桥静动载试验分析

摘要

Static-dynamic load test is an important means of inspecting load-bearing capacity and evaluating cur- rent condition of a bridge. This paper introduces the techniques of static-dynamic load tests on a multi-span PC continuous girder bridge which has been in operation in recent 30 years. Based on the comparison and analysis of test data and inspecting indicator, the load-bearing capacity was processed by comprehensive evaluation and appraisal, and a homologous treatment for practical disease condition of the bridge was suggested as well. It has certain reference value for the investigation and maintenance of such kind of bridges.%桥梁静动载试验是检验桥梁承载能力、评价桥梁现状的重要手段．文章以某运营了近30年的多跨Pc连续梁桥为背景，介绍了该桥静动载试验方法．根据试验数据和检验指标的对比分析，对桥梁的承载能力进行了综合评估与鉴定，并结合桥梁的实际病害状况提出了相应的处治建议．对同类型桥梁的检测与维护工作有一定的参考价值．
