摘　　要：选取矩形、直墙拱形、梯形、圆形和椭圆形5种断面形状的巷道进行了优化设计研究,基于有限元程序分析了5种典型断面巷道的应力应变关系及塑性区分布规律,并深入分析了不同侧压力系数对圆形/椭圆形断面巷道的影响,得出了一些有意义的结论。The rectangular,the straight wall arch,trapezoidal,circular and elliptical shapes of roadway were selected in this work. Based on fi-nite element method,the stress-strain relation and distribution of plastic zone of these five shapes of roadway were analysed. Influence of coeffi-cient of lateral pressure was also researched in this work,drew some meaningful conclusions.
