摘要: 介绍了Ｒａｙｌｅｉｇｈ波在工程勘察中的常用解释方法，分析了影响勘探精度的主要因素，并提出了一种简单的解释方法。利用两个不同模型的理论频散进行计算表明，即使模型中含明显的低速层，该方法所得剪切波速度结构与真实值也非常接近。对实测地震波处理所得结果与单孔测井所得结果也较为吻合。

Abstract: In this paper,we introduced common interpretation methods in Rayleigh wave exploration, analysed the primary factors of effecting on exploration precision,and provided a simple method of interpretation. The computation resulted from theoretical dispersion of two different kinds of model showed that shear wave structures obtained by this method are also coincident with true values, even if slow velocity layers are obviously included in the model.Moreover,the results obtained from observed waveform are very similar to those from single hole logging.
