邯郸市区场地土剪切波速与埋深相关性分析
|
摘要
收集了邯郸市区34个场地66个钻孔剪切波速资料,按土类别对所有剪切波速进行统计整理。采用线性Vs=a+bH、多项式Vs=a+bH+cH2及幂函数Vs=aHb对各类土剪切波速随深度变化进行了回归分析,给出了各类土剪切波速随深度变化的三种关系式及相应的回归参数。经对比分析表明,邯郸市区土层剪切波速与深度之间砂性土、粉土及粉质粘土宜采用多项式进行拟合;而粘土、卵石用幂函数拟合优于线性和多项式拟合。对邯郸市土工抗震工程中剪切波速的求取与应用具有重要的指导意义。
The shear wave velocity dates of 66 boreholes in 34 sites have been collected in Handan city,and all the shear wave velocities have been statistical sorted. This article took advantage of linear Vs = a + bH,polynomial Vs = a + bH + cH2 and exponential function Vs = aHbto regression analysis shear wave velocity along with the depth change. Then three types of relationships and the corresponding parameters of each kind of soil were obtained. By contrast,the result show that polynomial fitting method is better than both the linear fitting method and exponential fitting method between shear wave velocities and soil depths for sandy soil,silty soil and silty clay in Handan city; but exponential fitting method is better than the two other fitting method for clay and gravel. It has important directive significance to get and apply shear wave velocity in geotechnical earthquake engineering in Handan.
