摘　　要：通过讨论开挖释放荷载的Mana法和界面应力释放法,以具体工程算例给出了Marc中开挖荷载施加的途径,并给出了开挖释放荷载的获得途径;文中获得的开挖释放荷载的计算与施加方法为后续研究岩体的蠕变行为提供了可行的思路.This paper discusses Mana method of load release during excavation and release method of interface stress, and provides approaches to load release during excavation in Marc with concrete engineering examples. Thus, the calculation and imposition methods introduced in this paper provide a feasible method for the follow-up study on the creep behavior of rock mass.
