摘要
研究福建罗源湾淤泥做爆炸挤淤法处理软基扩腔过程数值模拟.考虑淤泥自身重力及其上部水的影响,用理想弹塑性模型模拟淤泥在爆炸压力作用下的力学性质,建立爆炸挤淤中扩腔过程的三维分析模型.通过对炸药挤淤的空腔扩展过程的数值模拟与扩腔过程的规律的分析,得出空腔扩展过程中关键点的位移、质点速度及空腔压力的变化规律.理论分析表明,所建模型是合理的.
The numerical simulation of the process of expanding cavity by blasting silt removal method for soft soil treatment in Fujian Luoyuan Bay is conducted. Considering the silt weight and water pressure, using elastic-ideal plastic model to simulate silt under explosion, the three-dimensional model to analyze the process of expanding cavity is established. The displacement, velocity and pressure of key points, are obtained. The simulation results indicate the model is reasonable.
