　　It is reported that this load test adopts the detection mode of static load + dynamic load to directly test the safety and reliability of the bridge structure. In the static load test, a total of 20 heavy trucks with a total weight of 700 tons were invested to simulate the working conditions of the bridge structure under extreme load conditions by grading the key sections of the bridge. The dynamic load test simulates complex situations such as high-speed driving and braking in the future, and comprehensively tests the performance of the bridge in the limit state. Through the preliminary analysis of the automatic collection of strain, deflection and other load test data, all indicators and parameters of the bridge meet the design standards, and the load test is successfully completed.

　　At present, the project has entered the pre-opening testing and acceptance stage, and the follow-up will speed up the finishing and supporting support work. (Reporter He Yixuan)
