摘　　要：为了揭示咸阳市区建筑场地土层的抗震性能,依据大量野外钻探及252个剪切波速测试孔实测资料分析,市区等效剪切波速介于208.73—306.26 m/s之间。根据土层等效剪切波速和场地覆盖层厚度把咸阳市区建筑场地类别划分为为两类(Ⅱ类和Ⅲ类)四区(Ⅱ1、Ⅱ2和Ⅲ1、Ⅲ2),采用内插法确定四个分区的特征周期依次为0.38 s、0.39 s、0.41 s和0.42 s。In order to reveal the seismic performance of the construction site＇ s mud layer in Xianyang urban ar- ea, under the analysis of huge amount of field drilling and observed data of 252 shear wave velocity testing hole, the urban equivalent shear wave velocity is between 208.73--306. 26 m/s. Xianyang urban area construction site is classified into two classes （ Class Ⅱ and Class Ⅲ ） and four districts （ Ⅱ 1, Ⅱ2 and Ⅲ1,Ⅲ2 ） according to the mud layer equivalent shear wave velocity and cover layer thickness of the ground, adopting the Interpolation method to ensure the four districts＇ Characteristic period is 0. 38 s,0. 39 s,0. 41 s and 0. 42 s in turn.
