The main contents of testing the strength of subgrade abamurus using earthquake wave velocity are as follows : the influence of the lithology and strength of flag stones and the shape of block upon wave velocity , the influence of the strength of cement mortar upon earthquake wave velocity , the estimation standards of the strength and completion of abamurus . this paper puts forward an accurate no - destructive testing using the different reflect of elastic wave velocity for abamurus stones , the strength of mortar , the plumpness of mortar and the type of abamurus , on the basis of laboratory tests and field tests . it can be used to accurately distinguish the completion of abamurus
地震波速法检测路基挡墙强度，研究的主要内容有：片石岩性和强度及块体形体对波速的影响；水泥砂浆强度对墙体波速的影响；挡墙整体强度和完整性的评估标准。应用弹性波速度对挡土墙石材、砂浆强度、砂浆饱满度及挡墙类型的不同反映，在室内外模型试验和现场生产试验的基础上，提出了一种正确的无损检测法，可以正确判别浆砂片石挡墙墙身的完整性。
