Title: $Static-dynamic load tests and analysis of a multi-span PC continuous girder bridge
Abstract: Static-dynamic load test is an important means of inspecting load-bearing capacity and evaluating current 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.
