土层的性质与剪切波速的关系

本文用多元逐步回归分析法和非线性模型参数确定法,对西安、徐州、鞍山等地的土层埋深及物理水理指标与剪切波速的关系进行了综合的分析和对比,结果显示深度和液性指数对剪切波速有明显的影响。作者认为,用非线性模型参数确定法有利于提高V_(?)经验公式的精度。

RELATIONS BETWEEN THE PROPERTIES OF SOIL LAYERS AND THE SHEAR WAVE VELOCITIES

In the paper,the author,according to the data of Xi''an,Xuzhou,Anshan and other places,has applied the multivariate step-by-step regression analysis and the deciding method of nonlinear model parameters to analyze comprehensivly the relations between the shear wave velocities and the depth and indexes of physical and water properties of soil layers,and contrast the relations of one region with other''s.The result that the depth and the index of liquid affect the shear velocity is concluded.And the author states that the deciding method of nonlinear model parameters can raise the precision of empirical formula of Vs.
