摘要：
In order to get a full understanding the whole bridge's actual stress state and dynamic performance as well as to check whether the bridge structure could meet the requirements of carrying capacity and traffic capacity, loading test has been carried out to the Nanxi Yangtze River Bridge. As the bridge is a long-span suspension bridge, there is a significant geometric non-linear effect which must be considered in the calculation. Besides, a reasonable field test organization scheme is necessary to guarantee the success of the test since there are a variety of working conditions and a large number of loading trucks. Finally, this kind of static and dynamic load test has a high guiding significance to the field test.
