| 摘 要： | 苗尾水电站导流隧洞进口岩体质量较差,倾倒变形严重,洞口开挖后,边坡倾倒变形加剧,产生许多张拉裂缝。通过采取合理的加固处理方案,使变形得到了有效的控制,裂缝没有进一步发展,确保了工程及施工安全。这不仅为工程建设本身赢得了宝贵的工期,还为国内类似工程积累了设计经验。

| Abstract: | In the diversion tunnel inlets of the Miaowei hydropower station,rock mass quality is poor and toppling deformation is severe.After the excavation of structural opening,the toppling deformation of inlets slope accelerates rapidly,many tensile cracks appear.For this,the reasonable reinforcement programs are put forward and then the effective control for the deformation is narrated,the cracks don’t expand further,the engineering and construction safety have been ensured after the reinforcement.This not only for the construction of the project itself has won valuable construction period,but also for similar projects at home and abroad accumulates design experience. |
