[提要]  无损检测混凝土强度的方法中，回弹法、超声回弹法在工程中应用较广泛。其中回弹法的可靠性较超声回弹法差。当采用两种方法检测评定且每一种方法的适用条件不能都满足时，如何合理可靠地评定结构的混凝土强度是一个实际问题。现采用Bayes方法对此进行了分析，取得了良好效果。

The codes of the rebound method and the ultrasonic rebound method have been established respectively in nonde-structive tests of concrete strength and applied extensively in engjneering practices on the spot. The reliability of the ultrasoruc rebound method is better than that of the rebound method.lt is a practical problem how to test and evaluate the concrete strength when the two methods are adopted and their applied conditions cannot be satisfied completely. The Bayes-based method isadopted to analyze the problem above and the result is reasonable.
