摘　　要：剪切波速是场地地震反应分析中的一个重要计算参数。针对工程中剪切波速测试不能达到技术要求的情况,本文简要分析了剪切波速测试不能达到要求的原因,并介绍了剪切波速推测作为弥补手段,使剪切波速达到技术要求。通过工程实例介绍了两种推测剪切波速的办法,一种是利用指数形式的经验公式推测剪切波速,主要是介绍了通过微调公式中的部分参数,使得推测结果更结合实际,另一种是利用多项式形式拟合来推测剪切波速,主要是通过观察其分布规律,来确定其拟合函数的形式。Shear wave is an important calculating parameter in site seismic response analysis. Sometimes, shear wave testing could not arrive at technical requirement, whose reasons are analyzed in this paper. As a remedy method, shear wave inferring is introduced in order to make the shear wave arrive at technical requirement. In the paper, two methods of inferring shear wave are introduced by some engineering applying, one is using exponential formed experience formula method to infer shear wave, mainly introducing how to infer shear wave more accurately using experience formula by little adjusting some parameters in the formula, the other one is using polynomial fitting method to infer shear wave, mainly introducing how to ascertain the function form by observing the distribution law of shear wave.
