摘　　要：以一个工程实例为例,探讨利用数值模拟监测值的突变特征来确定工程参数。综合考虑稳定性安全系数、特征部位位移量及受拉程度跟随工程工况的变化特征,推断工程结构的承载极限,从而确定合理的工程参数。与常用方法相比,该法受人为因素影响小,推断结果更为客观。研究方法列出了分析步骤,对类似工程问题的分析具有一定借鉴意义。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.
