| 摘 要： | 针对溪洛渡工程尾水洞的典型断面,利用平面有限元方法,计算分析施工期围岩开挖稳定问题,以及开挖、回填灌浆、调压涌浪作用下和施工渡汛期等工况下围岩、衬砌的应力分布情况.计算结果表明,在调压涌浪作用下,衬砌受到最大的拉应力作用,是控制性工况;隧洞底部转角处拉应力集中,建议进行局部修圆处理.

| Abstract: | Based on 2D finite element analysis,the stress of a typical section of the tailrace tunnel for Xiluodu Hydropower Station is conducted.It is found that the tensile stress is the biggest under surge pressure;and it is the dominant working condition for lining design.There are big tensile stress concentrations in bottom corners of linging;and local design improvement is needed. |
