本文提出了一种适用于任意横断面的地下岩洞动力计算的半解析半数值方法。此法将岩洞所在处的自由场应力状态和岩洞周壁应力状态联系起来进行分析计算,这较之有限元法节省了大量自由度、内存与计算工作量。文中还给出了有衬砌的地下岩洞动力计算方法。
This paper presents a semi-analytical semi-numerical method for dynamic calculation of underground caverns that is suitable for arbitrary cross-sections. This method relates the free-field stress state of the cavern to the stress state of the perimeter of the cavern for analysis and calculation, which saves a lot of freedom, memory and computational workload compared to the finite element method. The paper also gives a dynamic calculation method for lining underground caverns.
