| 摘 要： | 在文献[1]所建立的饱和砂土动力分析模型的基础上，将该模型编制成分析模块并与通用岩土分析软件FLAC接口。模拟分析饱和砂土在爆炸压缩波荷载作用下波的传播特性，分别考虑了准饱和砂土各组分含量等因素对饱和砂土中波传播的影响。数值模拟结果表明，准饱和土中含有的少量气体对爆炸压缩波传播以及饱和砂土动力特性具有重要影响。

| Abstract: | The analytically dynamic model of saturated sandy soil which is proposed by reference literature[1] is programmed and interfaced with the FLAC code. The characteristics of the propagation of stress wave in quasi-saturated sandy soil under explosive loading is simulated and analyzed, and the influence of the content of the phrase of quasi-saturated sandy soil on the propagation of stress wave in quasi -saturated sandy soil are considered. The results of numerical simulating indicate that the little of gas has important role on the propagation of explosive compression waves in quasi -saturated sandy soil and the dynamic characteristics of quasi -saturated sandy soil. |
