摘要
主要介绍利用SYC一Ⅱ型非金属声波探测仪研究人工冻土的物理力学性质与超声波传播特性之间的关系;通过回归方法建立起两者之间的参数关系及其函数式,以便利用声学参数指标替代力学指标来评价冻土,为现场快速测定提供可行性与依据.
The relationship between the physical and machanical character and the acoustical character of artificial frozen soil is studied by the experiment and analyzed by a regressive method. The result is useful for fast detection in practice.
