摘　　要：通过对某实际工程承载能力的确定,介绍了一种利用无损检测和静载试验联合确定资料缺失的在役桥梁实际承载能力的方法．研究表明,无损检测可以确定桥梁的混凝土强度、钢筋数量等技术参数,并可结合标准图进行计算,在计算的基础上进行静载试验确定桥梁实际承载能力,此项研究为今后类似工程提供了参考．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.
