| 摘 要： | 以爆炸密实砂基工程为背景，建立了简化的二维数学模型，采用简单的条带变网格技术，在微机上实现了爆炸密实饱和砂基气泡发展过程的数值模拟。研究表明，在饱和砂中爆炸高压气泡形状近似于球形（１０ｍ 范围内）对气泡形状影响不大，粘滞阻力初始阶段对高压气泡膨胀的运动规律没有明显影响。

| Abstract: | On the basis of blasting the dense sand base engineering,a simplified two dimensional mathematical model was established.The digital calculation of bubble expansion with the technology of simplified changcable strapping lattice was accomplished with success.The result shows that the high pressure bubble during the blast of saturated sand are approximately spheric in shape.The impact on the shape of bubbles is not so significant in the range of 10m.The viseosity resistance has no obvious impact on the mode of expansion for high pressure bubbles. |
