通过桥梁用钢示波冲击试验讨论了区分Wi、Wp与Wt的意义及其三者之间的关系,分析了试样的取样方向和试验温度对Wi、Wp与Wt值及其之间关系的影响。结果表明,L-T方向取样试样的Wt、Wp值均较大,Wi值变化没有规律性。Wp与Wt呈线性关系,不随试验温度和取样方向的改变而改变。Wt、Wp值随试验温度的降低而减小,Wi/Wt值随试验温度的降低而增加,均小于50%。
The significance of distinguishing between Wi, Wp and Wt and the relationship among the three were discussed through the steel oscillometric impact test of bridges. The relationship between the sampling direction and the test temperature on the W w and Wt values was analyzed influences. The results showed that the Wt and Wp values of L-T samples were all large, and the variation of Wi values was irregular. Wp and Wt linear relationship, does not change with the test temperature and sampling direction changes. The values of Wt and Wp decrease with the decrease of the test temperature, and the value of Wi / Wt increases with the decrease of the test temperature, all less than 50%.
