| 摘 要： | 有限元法具有计算精度高、对结构形状和荷载形式有良好的适应性等优点.有限元法把分析的连续体划分成许多较小单元,在单元之间满足线性方程,因此有限元法为非线性问题转化为线性问题提供了方法.基于有限元法开发的有限元软件具有划分有限元网格、计算隧洞围岩在开挖后的有限元各节点应力大小和变形位移、模拟围岩变形图、应力场分布和应力的流动等功能,为设计、开挖和维护隧洞提供了可行性方法.

| Abstract: | Finite element method has the merits of high precision, excellent adaptation to structure and load. It analyzes a continuous body by grinding units which satisfy linear equations. The refore, this method provides a way for transforming nonlinear problems into linear ones. The finite element soft ware on this basis has the function of grinding units, calculating the stress of every unit knot and the displacement of deformation after digging wall rocks, and simulating the graph of deformation and stress field distribution and stress flow thus providing a feasible method for designing, digging and protecting tunnel. |
