The research results show that crack length nearly has not influence on longitudinal wave velocity. 研究结果表明,波速随裂隙长度变化很不明显;
The results show that the longitudinal wave velocity is closely correlated to strain energy factor and exhibits the blastability of frozen soil. 结果表明,纵波速度(LWV)与变形能系数关联度最大,纵波速度(LWV)能较好地反映冻土的爆破性。
Based on the equation of stress wave, important characteristic parameters ( longitudinal wave velocity, transverse wave velocity, kink wave velocity and kink wave angle ) of stress wave is studied. 在应力波方程的基础上,研究了阻拦索应力波的重要特征参数(纵波波速、横波波速、弯折波波速和弯折角)。
Using SYC-2 type supersonic wave test instrument and 20 kHz energy transducer, the authors are able to measure the longitudinal wave velocity of frozen silty clay under different temperature and moisture conditions. 用SYC-2型超声波测试仪和20kHz超声换能器实测了不同温度和不同含水率下冻结粉质粘土的纵波波速,对实验数据进行了分析。
All studies show that weak plane inclination, thickness and whether be run through or not have a significant impact on longitudinal wave velocity, average modulus and strength of specimens. 研究结果表明:弱面的倾角、厚度及是否贯通等对试样的纵波速度(LWV)、平均模量和强度具有显著的影响。
