The dynamic load test and analysis of a bridge on sandy soil foundation

The dynamic load test is an important means of bridge quality testing. Through dynamic load tests to evaluate that the autooscillation characteristics of bridge structure, and the combination vibration characteristics of vehicle dynamic loading and bridge structure forced vibration. The test data are the main indexes of judging the bridge structure operational status and load-bearing characteristics. In this thesis, we in combination with an actual case of bridge test, emphatically analyzes the testing content and safety appraisal of dynamic load test. In this way, providing some references for the later dynamic load test of bridge detection.
