弹体侵入岩体的一种工程计算方法

常规深钻地武器的迅猛发展给防护工程设计带来了新的挑战，需要一种更加合理的弹性侵入岩体的工程计算方法。根据工程岩体分类系统建议岩体的强度理论模型，利用空腔膨胀理论计算弹头侵入岩体时的侵彻阻力，根据牛顿定律确定弹体侵入岩体时的运动方程，提出了弹体侵入岩体的工程计算方法，并对该算法进行了验证和讨论，验算结果与试验数据相吻合。同时，由于引用了岩体构造特征参数，使得弹体侵入岩体的工程计算方法更具有合理性和实用性。

Engineering Method for Calculating the Penetration Depth into Rocks

With the development of projectiles, a new engineering method for calculating the penetration depth in rocks is needed. In this paper, the strength of rock body obeys the RMR system. This suggestion is adopted in the cavity expansion theory to calculate the reaction force of the projectile. And the motion of the projectile into rocks can be described by the Newton Laws. So in the end, an engineering method is suggested for calculating the penetration depth into rocks. This mehod is preliminarily checked up in combination with the test date. And the method proves reasonable and practical.
