多道瞬态瑞利波在不均匀介质中传播时,会产生频散现象,即波速随着波长产生变化;而这变化关系跟地下地质情况之间有着内在的联系,通过对频散曲线的分析,可以对岩土的物理性质作出评价。瑞利面波勘探法对场地要求不高,方法简单快捷,易于激发和识别,有效信号能量强,广泛应用于各种工程领域。强夯法对地层的加固效果是施工中重要的一环,多道瞬态瑞利波检测技术的应用有效地实现了这一过程。
Multi-channel transient Rayleigh wave propagation in the uneven medium, will produce the phenomenon of dispersion, that is, the wave velocity changes with the wavelength; and the relationship between this change and the underlying geological conditions are intrinsically linked to the dispersion curve Analysis, the physical properties of rock and soil can be evaluated. Rayleigh surface wave exploration method on the site less demanding, the method is simple and quick, easy to stimulate and identify the effective signal energy, widely used in various fields of engineering. The effect of dynamic compaction on the stratum reinforcement is an important part of the construction. The application of multichannel transient Rayleigh wave detection technology has effectively realized this process.
