【摘要】 随着现代科学技术的进步,桥梁结构的设计方法和设计理论都有了根本性的变化,然而影响桥梁工程质量的许多不确定因素仍然存在,为检验建成后的桥梁工程质量,以重庆菜园坝长江大桥为实例,用载重汽车与轻轨车辆同时试验模拟设计荷载,合理的合并试验工况,对实桥进行静载试验,了解桥梁结构在试验荷载作用下的实际工作状态,进而评估桥梁结构的施工质量和使用状况,为竣工验收和深入探索提供科学依据。更多还原

【Abstract】 With the development of science and technology,fundamental changes have emerged in the design methods and design theory of bridge structure.Yet,there are a lot of factors affecting the quality of a project.In order to test construction quality of the built bridge,taking CaiyuanbaYangtze Bridge as an example,heavy trucks and light rail vehicles have been used to simulate the design loads.Test conditions have been reasonably combined and the static loading tests were made over the real bridge.The tests help to understand the bridge under the real working condition and help to evaluate the construction quality of bridge structure and using safety,which provide scientific basis for the final acceptance of the construction and in-depth exploration.更多还原
