衡水市岩土体剪切波速与土层深度的关系
|
摘要
土体剪切波速在岩土地震工程中应用广泛。选取衡水市城区82个典型钻孔的岩土体剪切波速资料,采用三种数学模型进行统计回归分析,利用拟合优度R2值检验回归方程对观测数据的拟合程度。统计结果表明,该地区各类岩土体剪切波速与埋深存在明显的线性相关关系。分别给出了不分土体类别和区分土体类别两种情况下最优统计关系式。利用实际工程钻孔进行剪切波速预测与检验。检验结果表明,给出的各类岩土体的剪切波速与埋深经验关系是可靠的,可用于衡水市城区地下100 m深度范围内的剪切波速计算。
The shear wave velocity of soils is widely used in the field of geotechnical earthquake engineering.The data of shear wave velocity of soils from 82 typical boreholes in urban area of Hengshui city for regressive statistic analyses with three mathematical models was selected. The correlation coefficient R2 was used to verify the linear correlation between the shear wave velocity and depth. The regressive statistic analyses show that the shear wave velocity and depth of soils in the district is remarkably correlated linearly. According to two cases with and without considering soil classification,the fittest function between the shear wave velocity and depth of soils in urban area of Hengshui city are obtained. The estimation of the shear wave velocity of soils from a testing borehole has shown that the empirical relation between the shear wave velocity and depth of soils in the district is reliable. A conclution is draw that the empirical relations between the shear wave velocity and depth of soils of Hengshui city are reliable,which can be used to predict the shear wave velocity of urban area of Hengshui city in the range of 100 m depth.
