文章结合已运营了近20年的某桁架拱桥静载试验,介绍了桁架拱桥承载能力评定过程中的调查与检测、桥梁结构验算、静载试验及承载能力评定,较详细地阐述了静载试验方法及试验结果分析,对该类桥梁的静载试验与结构评定提供有益的参考。 Based on the static load test of a truss arch bridge which has been in operation for nearly 20 years, the article introduces the investigation and testing during the assessment of truss arch bridge carrying capacity, the checking of the bridge structure, the static load test and the assessment of carrying capacity. The static load test Methods and test results analysis, provide a useful reference for the static load test and structural evaluation of such bridges.
