本文介绍了对一系列混凝土试件进行的静态和动态试验，以确定泊松比的值。确定了三个比值，即静态值和由动态试验得出的两个值。在可能的情况下，这些值彼此相关，并与混凝土的其他属性相关。还比较了两种试验测得的弹性模量值。根据动态试验的结果，推导出由超声脉冲速度的测量结果确定动弹模数的公式。
Summary This paper describes static and dynamic tests carried out on a series of concrete specimens to determine the values of Poisson's ratio. Three values of the ratio were determined, the static value and two values derived from the dynamic tests. Where possible the values are related to each other and to other properties of the concrete. Values of the elastic moduli determined from both types of tests are also compared. From the results of the dynamic tests an equation is derived by which the dynamic elastic modulus may be determined from measurements of the ultrasonic pulse velocity.
