爆炸排淤填石法的数值计算研究

Numerical Simulation of Toe-shooting Method

利用数值模拟软件AUTODYN对爆炸排淤这一工程实际问题进行模拟分析,得到了一定药量与埋深下淤泥内部压力变化情况。通过数值模拟得出淤泥与石块的运动规律。该种模拟分析手段对实际工程中药量、埋深的选取具有一定的参考作用。

In this paper, AUTODYN the numerical simulation software is used to simulate the engineering problem of discharging silt by explosion. By this method,change of internal pressure in silt at a certain quality and depth is obvious. The movement of silt and rock is obtained by numerical simulation.This kind of simulation analysis method provides reference for the selection of quality and depth in actual project.
