摘　　要：基于西安市阎良区19个工程地质钻孔约1040测点的剪切波速资料,利用指数形式的剪切波速经验公式,对测点较多的黄土状土、粉质粘土、粉土和粉、细砂四类土的剪切波速进行了统计分析,得到这四类土剪切波速沿深度一般变化规律的经验公式。The shear wave data of 1040 testing points has been gotten from 19 engineering geology drilling holes in Yanliang District, Xi＇ an City. Because of more testing points for loess-like soil, silty clay, silts, and fine sand, shear wave data of the four sorts of soil are analyzed statistically, using exponential-formed shear wave experience formula. Then the experience formulae of shear wave for the four types of soil are obtained, which could show the common rules that shear wave changes along with the depth.
