【摘要】 鲁西平原地区属黄河冲积平原,地势平坦,工程地质情况较单一,场地类别以Ⅲ类场地为主。利用鲁西平原地区常见土类的剪切波速与埋深的数据,使用4种回归模型建立了它们之间的经验关系式,并对这些经验式的合理性进行了讨论。结果表明:鲁西平原地区常见土类的剪切波速与埋深之间有明显的相关性,基于幂函数的回归模型(v_si=ah■+c)得到的经验关系式拟合效果最佳,具有较好的应用价值。更多还原

【Abstract】 Plain area of western Shandong which belongs to the Yellow River alluvial plain is flat and has simple engineering geological condition, and site category in the area is given priority to Ⅲ class in Chinese Code for Seismic Design of Buildings. Using data of shear wave velocity and depth of common soils in the plain area, empirical relationships between them were established by using 4 regression models, and the rationalities of these empirical relationships were discussed respectively. The results show that there are obvious correlations between shear wave velocity and depth of common soils in the plain area, and the fitting effect of the empirical formulas obtained by the regression model based on power function(v_si=ah■+c) is the best, and the formulas have good application value.更多还原
