| 摘 要： | 通过对西宁市区67个钻孔剪切波速资料整理，采用最小二乘法进行统计回归分析，得到西宁市土层剪切波速Vs随土层埋深H的经验关系式，西宁市典型土类Vs与H的经验关系。并且通过实测剪切波速与预测剪切波速的对比，验证所得经验关系式的适用性。

| Abstract: | The data of sheafing wave velocity of 67 bore holes in Xining area are analyzed, and the empirical relation of the velocity （ Vs ） and the depth （H） is got by least square regression method. And comparison of the actual shearing wave velocity and the forecast velocity, the empirical relation is tested and verified to be applicable. |
