摘要
分析了旧水泥混凝土路面板底脱空形成的机理和危害,评价了外观经验法、贝克曼梁弯沉法、落锤式弯沉仪法和探地雷达法等方法的脱空检测原理、特点和适用范围,并探讨了今后脱空检测技术的发展方向。
The mechanism and hazard of cavity beneath the cement concrete pavement slabs were analyzed.The principles and characteristics of three testing methods including empirical law,falling weight deflector and ground penetrating radar were evaluated,and the development of cavity testing method in future was discussed.
