摘    要:利用自行设计的室内土样剪切波速简便试验装置与测试方法对土样进行不同应力条件下剪切波速的测试.研究表明:剪切波速与土体的密度具有良好的相关性;剪切波速随含水量(大于20%)的减小而增大;当应力≤300 kPa时,剪切波速随压力的增大而大幅增值;应力>300kPa时,剪切波速增长缓慢.

关 键 词:土体剪切波速  超声波  应力  密度  含水量

Abstract:The shear wave velocity of soil samples are tested under stress condition by using a self-made indoor ultrasonic wave test facility and operational procedure.The results show that the shear wave velocity is related strongly to the density of soil.The shear wave velocity increases with the decrease of water content(>20%).When the stress is less than or equal to 300 kPa,the shear wave velocity increases a lot with the increase of the pressure.It increases a little when the stress is more than 300 kPa.
Keywords:soil mass  shear wave velocity  ultrasonic wave  stress  density  moisture content
