用无损检测和静载试验方法联合确定在役桥梁实际承载能力的研究

桥梁的实际承载能力通常是通过静载试验来确定 的.然而，当桥梁结构的设计资料丢失时，试验荷载的 确定就有一定的困难.此时，可以首先利用无损检测的 方法确定结构的材料和截面的参数，并以此为依据完 成相应的计算工作，然后利用计算结果指导试验，通过 静载试验最终完成桥梁

Research on using combination of non-destructive test and dead load test to determine actual bearing capacity of bridge in service

Through determination of bearing capacity of a real project, a method which combines non-destructive test with the dead load test to determine the actual bearing capacity of bridge structure without enough technical data is introduced. The study shows that the method of non-destructive test can determine the technical partameters of real bridges, such as the strength of concrete,amount of steel bars, etc. , which could be used in computing combined with the standard drawings. And on that basis, the bearing capacity of real bridge can be determined by dead load test. The research provides a reference to forecasting similar projects.
