摘要
通过对厚宽比和几何形状系数已有关系进行总结,并在此基础上,进行补充试验,同时分析了测试对象的几何形状系数对波速测试结果的影响,得出了在隧道、路面等结构厚度测试中几何形状系数的参考取值,为反射法在路面厚度、隧道衬砌厚度、楼板厚度的声速修正提供了参考依据。
Through the summary on existing correlation coefficient of width and thickness ratio and geometricalshape factor, the supplementary test is performed on this basis. Meanwhile, the influence of geometrical shape factor of testing object on the testing result of wave velocity is analyzed, so as to obtain the reference value ofgeometrical shape factor in thickness test on structures like tunnel, pavement and so on. Consequently, reference bases are provided for reflection method in the matter of sound velocity correction of pavement thickness, tunnel lining thickness and floor slab thickness.
