摘要
采用超声波技术测定冻土动弹性力学指标正是目前冻土学术界及工程领域致力研究的一个热点。本文将基于日产UVM -2型声速仪对冻结哈尔滨粉质黏土超声波速测定结果 。
Nowdays, it is just a hotspot in the field of frozen soil how to measure the dynamic elastic mechanical indexes of the frozen soil using ultrasonic technology.This paper will mainly discuss the influence of temperature below centigrade zero and water content upon the spreading velocity of ultrasonic in the frozen soil and the dynamic elastic mechanical indexes of the frozen soil based on the measured results of ultrasonic velocity in frozen Harbin silty clay by Japanese UVM-2 ultrasonoscope.
