摘要
基于廊坊地区地震安全性评价中所获得的实测钻孔资料,利用多种一元回归模型对地区内常规土类埋深与剪切波速间相关性进行统计研究,通过对比分析,推荐得出不同土类二者间相关性的最优选择,同时探讨了土体状态对二者相关性的影响。结果表明:(1)区域内各常见土类(除人工填土外)剪切波速与埋深间存在联系,且离散程度随埋藏深度增大而增大;(2)本文模型较刘红帅给出的推荐模型更为接近实测数据;(3)区域性对剪切波速与埋深之间的相关性存在影响。
Based on the measured borehole data obtained in the seismic safety evaluation of Langfang area,Hebei Province,the correlation between the burial depth of conventional soil and the shear wave velocity in the area was statistically studied by using a variety of one variable regression models.Through comparative analysis,the optimal choice of the correlation between different soil types was recommended.At the same time,the influence of soil state on the correlation between the two was discussed.The results show these as follows.There is a relationship between shear wave velocity and buried depth of common soils(except for artificial fill),and the degree of dispersion increases with the increase of burial depth.The recommended model is closer to the measured data than the recommended model given by Liu Hongshuai.The regional effects have an effect on the correlation between the shear are velocity and burying depth.
