Abstract: Based on an engineering example, this paper explored a method to determine engineering parameters by utilizing mutable characteristics of monitored values during numerical simulation. The carrying capacity limit of engineering structure was inferred and engineering parameters were reasonably determined, based on comprehensively considering variation features of stability safety factor, displacement and tensile stress in characteristic position along with the change of engineering condition. Compared with common ways, this method was less effected by human factors, which meant more objective result. Analysis steps of this research method are listed in the paper, which provided analysis of similar engineering problems with some learning experiences.

Key words: mining engineering, numerical simulation, mutability, FLAC3D, stability analysis
