摘要
文中结合实例,研究了单孔检层法在岩土层剪切波速测试中的应用,利用单孔检层法,以地面重锤激振方式,生成剪切波,通过检波器采集振动信号,求解剪切波速。试验结果表明,该区域拟建工程场地类别为III类,岩土层类型属于中软土,各钻孔岩土层的剪切波速均值在152.6~248.8m/s之间,且测试深度与剪切波速成正比。
In this paper, the application of the single hole layer inspection method in the shear wave velocity measurement of rock and soil layers is studied with examples. The single hole layer inspection method is used to generate the shear wave in the way of ground hammer excitation, and the vibration signal is collected by the geophone to solve the shear wave velocity. The test results show that the proposed project site in this area belongs to class III, and the rock and soil layers belong to medium soft soil. The average shear wave velocity of rock and soil layers in each borehole is 152.6~248.8m/s, and the test depth is directly proportional to the shear wave velocity.
