| 摘 要： | 隧洞的围岩稳定及支护结构安全是保证隧洞安全、实现隧洞功能的关键因素。由围岩加固圈承担主要的外水压力是优化支护结构设计、保证围岩稳定的一种有效方法。建立肯斯瓦特导流泄洪洞三维有限元模型,并进行非线性有限元分析。分析结果表明,设计的支护措施能明显减少围岩变形、改善应力分布,为类似工程设计提供参考。

| Abstract: | The stability of surrounding rock tunnel and the safe of to ensure tunnels safe and to achieve tunnel function. It is a optimized support structure is the key factor design to exert major external water pressure at reinforce circle also it is an effective method for the stability of surrounding rock. The author did the nonlinear finite element analysis by creating three-dimensional finite element model of Kensiwate diversion spillway tunnel. The results show that the designed support measures can significantly reduce the rock deformation and improve the stress distribution, and it can provide a reference for the design of similar projects. |
