摘要
讨论超声波法在半刚性材料、水泥材料及聚合物改性水泥材料等公路工程土工材料研究中的应用 ,发现超声波法除可测定材料的动弹性模量等力学性能外 ,还可利用波形和波速等研究材料破坏断裂的过程及破坏情况 ;超声波法测定材料的动弹性模量与静力试验测定的弹性模量等静力学参数存在一定的关系。
This paper discusses the application of ultrasonic wave in studying the highway engineering materials such as half-rigid materials,cement materials and Polymer modified cement materials.The dynamic elastic module can be measurted by ultrasonic wave.The wave?from speed can be used to study the process and the degree of broken damage.There are certain relations between the dynamic elastic module measured with ultrasonic wave and the static elastic module measured by static test.
