摘要
利用现阶段国内外流行的岩土数值分析软件FLAC3D,模拟分析了圆形隧道围岩不同阶段的应力和位移,并把数值解和理论解析解进行了对比;分析了剪胀性对于隧道围岩应力位移的影响,对隧道工程的设计和施工有指导作用和参考价值。
Stress and displacement of the circular tunnel were simulated using the popular geotechnical numerical analysis software FLAC3D. Numerical solution was compared with and theoretical one, and the influence of shear dilatation on the stress and displacement. Results show that numerical simulation is helpful for the design and construction of the tunnel engineering.
