摘　　要：已有的理论和试验研究主要解决的是裂缝的宽度检测,裂缝深度检测技术仍然是当今最热门的研究课题。文章介绍了超声平测法检测钢筋混凝土结构裂缝深度的基本原理,在此基础上推导了超声波在经过钢筋混凝土中的传播速度计算式;并验证了计算公式和试验原理的可行性;最后讨论了该检测方法的适用范围。Experiments are made in order to determine the crack depth in reinforced concrete structure by the ultrasonic testing method. The testing principle is described, and the velocity formula of ultrasonic waves transmitting in reinforced-concrete is deduced. The experimental results are analyzed, which proves that the presented formulas and testing principle are feasible. The applicable range of this ultrasonic method is also discussed.
