既有混凝土拱桥的荷载试验及承载能力评估

The Load Test and Bearing Capacity Evaluation of Existing Concrete Arch Bridge

针对运营多年的某混凝土拱桥出现的一些病害,按最不利工况进行静载试验,并对其承载力进行了评估。根据检测结果,对该桥目前的整体状况、工作状态,及其使用情况做出综合评价,以期对同类现有桥梁的检测和维护起到借鉴作用。

For some diseases of a concrete arch bridge operating many years, according to the most unfavorable condition,this paper did the static load test and gave the assessment of the bearing capacity. According to the test results, it made the comprehensive evaluation of the current overall situation, bridge working state and its application. It provided reference for testing and maintenance of the similar existing bridges.
