摘要

提出了一种用多边形逼近滞回曲线计算土的阻尼比的方法，该方法可直接利用试验数据进行计算，算法可重复利用，使得阻尼比的计算工作得以简化。将其与传统的椭圆拟合方法计算结果进行了对比，由于实测的滞回圈不是标准的椭圆，两者的计算结果存在一定的差异。

Abstract

By replacing the dynamic stress-strain hysteresis loop with polygon

a simple method of determining the damping ratio of soils approximately is proposed. The method can use test results directly

and by using this method

the process of detemining damping ratio will be simplified. Then the results determined by this method and the traditional ellipse pseudo method are compared

differences are found between them because the actual hysteresis loop recorded in dynamic triaxial tests are not standard ellipse.
