【摘要】 根据运城市城区地震小区化建设项目中72个土层的剪切波速测试资料,采用幂函数模型对粉土、粉砂、粉黏土、细砂的土层剪切波速与埋深进行加权回归分析,得到不同土类的模型参数及拟合优度指标。将土层剪切波速预测值与实测值进行对比,验证了回归关系式的合理性和适用性。土层剪切波速与埋深呈较好的幂函数关系,拟合优度均在0.9以上。更多还原

【Abstract】 Based on data of shear wave velocities measured from 72 Yuncheng districts,the paper does the weighted regression analysis for shear wave velocity and depth of soils with various of soil type,including silt,silty sand,silty clay,fine sand,by using the power function model,and gets the model parameters of different soil types and goodness of fit index.Finally,the paper verifies the rationality and applicability of the regression equations via comparing measured values with the predicted values.The results show that there is power function relation between the sheaf wave velocities and the depths of soils in Yuncheng,and the goodness of fit is over 0.9.更多还原
