介绍了Rayleigh波的基本特征和测试原理,给出了某山区高填方机场地基采用Rayleigh波检测的实例。Rayleigh波测试数据表明,采用2000kN.m夯击能的地基有效加固深度为3.0m~4.4m,采用3000kN.m夯击能的地基有效加固深度为4.0m~4.5m。实例结果证明Rayleigh波法是一种经济、快捷且适用范围广泛的原位测试技术,用Rayleigh波检测山区高填方机场地基是可行的。
The basic characteristics and testing principles of Rayleigh wave are introduced. An example of using Rayleigh wave to detect the ground of a high-fill airport in a mountain area is given. Rayleigh wave test data show that the effective reinforcement depth of ground with 2000kN.m tamping energy is 3.0m ~ 4.4m, effective reinforcement depth of ground with 3000kN.m tamping energy is 4.0m ~ 4.5m. The results show that the Rayleigh wave method is an economical, fast and widely applicable in situ testing technique. Rayleigh wave detection of high-fill airport ground in mountainous areas is feasible.
