介绍了以实测围岩位移为依据反算作用于支护上的围岩压力的基本原理，同时为考虑塑性区的影响建立了弹塑性模型，并对计算结果利用各种图形和数据的方式来进行后处理，增加了可视性，它是预测、分析围岩压力，应力与变形非常有效的数值方法．
In this paper, the basic principle of calculating the surrounding rock pressure acting on the support based on the measured displacements of the surrounding rock is introduced. At the same time, an elastic-plastic model is established to consider the influence of the plastic zone, and various figures and data are used to calculate the result Post-processing, increase the visibility, it is predicted, analysis of wall pressure, stress and deformation is very effective numerical method.
