- Finally , in section three , rayleigh wave exploration method is used in a practical project - northern stone material trade market . the embedded depth of cobble substratum of the whole site , and the regression equation between the test blow count ( n63 ) standard penetration and the surface wave velocity ( vr ) are obtained in the process . a good case study is provided for the practice of the subjected method in this section
第三部分是将瑞雷波法勘探应用于北方石材交易市场的工程实际中，得到整个场地的下卧卵石层的埋藏深度，并给出该场地的标贯值n _ ( 63 . 5 )与v _ r间的回归方程，为这一方法的应用提供了很好的工程实例。 - In the thesis domestic and foreign relation model of standard penetration blow count and shearing velocity , standard penetration blow count and deformation modular , shearing velocity and foundation bearing capacity are analyzed . on base of these analysis a new calculation model that applying rayleigh wave velocity to calculate the stress ratio of pile and soil between piles is established . because of the difference of region and soil character , the new model own three branch model , ie , japan model , wuhan model , xia liaohe mo del , in three different conditions
文章通过分析国内外标准贯入击数与剪切波速、标准贯入击数与变形模量、剪切波速与地基土承载力之间的关系模型，并考虑到地区性和土质类别的差异，分别选用日本公路桥梁抗震设计新规程模型(日本模型) 、武汉地区模型、下辽河平原模型三种模型建立了新的桩土应力比计算模型? ?应用瑞雷波速求解桩土应力比之间的计算模型。
