依据试验结果，本文对岩土材料的剪胀和应变软化特性进行了恰当的简化后，利用弹塑性理论和体积平衡原理，推导出能反映岩上体的剪胀和应变软化的岩土体内扩孔问题的全部解析解，讨论了岩土的扩容和剪胀对扩孔结果的影响，并对一些工程现象进行了解释。
Based on the experimental results, the dilatancy and strain-softening characteristics of rock and soil materials are appropriately simplified, and the elasto-plastic theory and the principle of volume balance are used to derive the borehole reaming that can reflect the dilatancy and strain softening of the rock upper body. The full analytical solution of the problem discussed the effect of rock expansion and dilatancy on the results of hole expansion, and explained some engineering phenomena.
