摘　　要：在爆炸荷载作用下,岩体洞室通常采用喷锚支护结构和整体被复结构。通过理论研究,给出了平面应变条件下圆形洞室动力分析的解析解,并对不同结构厚度及不同坚硬岩体进行了计算,得到符合宏观定性分析的计算结果,通过一组试验算例检验了该方法的正确性。Under the explosive load, shotcrete and rock bolt support and integral lining structures are usually used for chambers in rock mass. The analytic solution for dynamic analysis of circular chambers under the plane strain is presented through theoretical research; and different structural thicknesses and different stiffnesses of rock masses are calculated. The obtained results are accordant with those of macroscopic qualitative analysis and can provide a valuable reference to verifying validity of numerical calculations.
