介绍了水泥土抗压强度的声波探测技术 ,研究分析了水泥土单轴抗压强度与纵波速度、横波速度的关系 ,并对试验结果进行了回归分析。试验结果表明 ,用声波技术对水泥土的质量进行检测是切实可行的 ;水泥土的单轴抗压强度与纵波速度、横波速度之间确实存在相关关系 ;水泥土的单轴抗压强度越高 ;波速越高 ;单轴抗压强度为波速的函数 。

This paper mainly introduces the ultrasonic check of the single axis compressing strength of the cement soil,and analyzes the relationship between the single axis compressing strength and the primary velocity and the secondary velocity.Moreover,it analyzes mathematical statistics data obtained in the experiment .The research shows that it is feasible to check the quality of the cement soil by the ultrasonic technology.It also proves that there is the correlativity between the single axis compressing strength and the primary velocity and the secondary velocity.It is found that the higher the single axis compressing strength of the cement soil,the higher the ultrasonic velocity and that the correlation of the compressing strength and ultrasonic velocity is exponent function.
