| 摘 要： | 为了解决当前风积沙路基压实度检测的难题,引进了瑞利波检测技术,并进行了风积沙路基瑞利波现场试验.研究认为,风积沙路基呈典型的水平层状介质模型,满足瑞利波检测的物理条件.分析了瑞利波检测压实度的原理,进行了现场瑞利波检测风积沙路基的试验,建立了瑞利波检测压实度的回归方程.进行了环刀法和瑞利波法检测结果的对比研究,认为瑞利波法自动化程度高,人为影响因素小,测试数据较准确,检测过程对路基质量没有损坏,属于无损原位检测.

| Abstract: | In order to solve the problem of aeolian sand subgrade compaction degree test,the method of Rayleigh wave is put forward,which has been performed at a desert highway construction site.Based on the characteristics of Rayleigh wave,it is concluded that the wave can be used in the compaction degree test.By analyzing the physical feature of aeolian sand subgrade,which is a typical,aclinic and laminar structure,the auttors advance the feasible method of Rayleigh wave.From the field test data,the regression equat... |
