近年来,建立在伏拉索夫(О.Е.Власов)理论基础上的水电模拟法已广泛地用来研究水利、爆炸对岩石的作用等问题。伏民把爆破介质看作不可压缩的理想流体,炸药爆炸的能量以动能的形式在瞬间传递给周围介质,在传递瞬间周围介质来不及发生位移,能量传递结束后介质内各质点获得不同的速度,质点的速度为介质破坏的决定因素。根据伏民的推导,爆炸速度势函数和电场的分布同样的能够满足拉普拉斯方程,这就能在模拟的基础上,利用电场来模拟爆破速度场,速度场可以给出介质中爆炸能的
In recent years, hydropower simulation based on the theory of ОЕЕВласов has been widely used to study the problems of water conservancy and the effects of explosions on rocks. Fu Min regarded the blasting medium as an incompressible ideal fluid. The energy of the explosives was transferred to the surrounding medium in the form of kinetic energy in an instant. At the moment of transfer, the surrounding medium could not move in time. After the energy transfer, the various points in the medium obtained different velocities, The speed of the particles is the decisive factor for the destruction of the media. According to Fu Min’s deduction, the explosive velocity potential function and the electric field distribution can satisfy the same Laplace equation, which can simulate the blasting velocity field by using the electric field based on the simulation. The velocity field can give the explosion energy in the medium of
