| 摘 要： | 本文以岩体的全应力－应变曲线为基础，建立了反映岩体出现塑性破坏后强度降低特点的力学模型，得到了巷道围岩塑性区半径和应力的明确解答．通过与现有其它力学模型的比较证明．本文提出的巷道围岩塑性区半径计算公式更为合理可靠．有更广泛的适用性．

| Abstract: | This paped Puts forward a elasto plastic strength softening mechanital model based on the stress-strain curve of rockmass to Calculate the plastic zone radius and stresses around a circle tunnel. It is demonstrated that the solutions in this peper are more rational and reliable than those from the other models such as Kastner's and Airey's so far. |
