水封爆破中水塞运动规律的理论解

Theoretical Solution on Movement of Water Stemming In Water Blasting

本文计及水在高速运动时与壁面的摩擦阻力，建立了水封爆破水塞运动的物理模型。由特征线方法及流体动力学基本理论给出了水封爆破中水塞运动的基本方程。特别给出了爆轰产物的γ＝３时水塞运动的理论解。

Considering the friction of borehole wall against water moving with high speed,a physical model of water stemming movement in water blasting is set up in this paper.According to the method of feature line and basic theory of hydrodynamics,the basic equation of water stemming movement in water blasting is developed.Theoretical solution of this movement is especially given when γ of the blasting products equals 3.
