| 摘 要： | 采用基于连续介质的块体离散元程序(CDEM)模拟结构面处应力波传播过程,用相关系数来描述应力波在结构面处发生的波形变化,研究了单结构面对波形变化的影响范围。研究表明:相关系数和透射系数在结构面处的变化规律是一致的,可以有效反映波形在结构面处的变化,单结构面对4倍波长范围内的测点波形有明显影响。

| Abstract: | Transmission process of stress wave in interface is simulated by adopt Continuous-based Discrete Element Method (CDEM),the wave form variation of stress wave in interface is described by correlation coefficient,and the range of wave form variation influenced by single interface is analyzed. Studies results demonstrate that the variation rule of correlation coefficient and transmission coefficient in interface are the same,could reflect the waveform changes in interface effectively; the single interface has ... |
