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。
選取矩形、直牆拱形、梯形、圓形和橢圓形5種斷麵形狀的巷道進行瞭優化設計研究,基于有限元程序分析瞭5種典型斷麵巷道的應力應變關繫及塑性區分佈規律,併深入分析瞭不同側壓力繫數對圓形/橢圓形斷麵巷道的影響,得齣瞭一些有意義的結論。

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.
