近年来,随着勘探技术的发展和勘探实际需要,人们逐渐开始加强对瑞雷面波的关注和重视程度,其具备起点低、迅速、成本低廉、容易识别、受地层影响不明显等鲜明特征,使得其可以广泛的应用在公路、铁路等共层的地层勘探中,而软岩地层涵盖第四系松散层,地层组成比较复杂,在进行工程勘探时普通的勘探方法已经逐渐满足不了其发展的需求,而瑞雷面波超强的分辨和识别能力在对软岩地层勘探有明显的优势。本文首先介绍瞬态瑞雷波的特征和展开方法;其次,结合具体的工程实例,进行瑞雷面波解决软岩地层勘探的实际问题;最后,笔者对瞬态瑞雷面波法在软岩地层勘探中的应用进行总结。
In recent years, with the development of exploration technology and the actual needs of exploration, people gradually began to pay more attention to and pay more attention to the Rayleigh wave. They have such distinctive features as low starting point, rapidness, low cost, easy identification and insignificant influence by formation , Making it widely used in stratigraphic exploration of road, railway and other layers, while the soft rock strata cover the Quaternary loose strata. The stratum composition is quite complex. Ordinary exploration methods have been unable to meet its development gradually during engineering exploration Demand, Rayleigh surface wave super resolution and identification ability of soft rock formation exploration has obvious advantages. In this paper, firstly, the characteristics and development of transient Rayleigh wave are introduced. Secondly, the practical problems of Rayleigh wave surface exploration in soft rock formation are analyzed with concrete engineering examples. Finally, The application of stratigraphic exploration is summarized.
