【摘要】 利用长治市区工程场地地震安全性评价项目中已完成的43个钻孔及剪切波速测井资料,基于克里金插值方法,构建长治市区浅部地层及剪切波速度结构模型。结果表明,长治市区浅部地层及剪切波速具有较强的横向非均匀性结构特征,其沉积建造明显受水文地质环境及主要断裂的控制。更多还原

【Abstract】 Using drilling and shear wave velocity logging data collected from 43 engineering sites of seismic safety evaluation projects completed in Changzhi urban district,the structural models of shallow strata and shear wave velocity are built in terms of the Kriging interpolation,which is an unbiased evaluation method for non-uniform distribution of discrete data.The results show that the shallow strata and shear wave velocity structures present stronger laterally inhomogeneous features,and also indicate that the sedimentary deformation is obviously controlled by the hydrological environment as well as the main faults in Changzhi urban district and its adjacent areas.更多还原
