摘要
龙滩水电站进水口高边坡是典型的反倾向层状结构岩质边坡。边坡最大组合坡高达420m,上游与倾倒蠕变岩体自然边坡连成一体,坡脚布置有9条大直径引水隧洞,其下与导流洞进口开挖区连成一片,形成轮廓复杂的高边坡。蠕变岩体边坡与进水口开挖边坡的稳定直接关系到电站的顺利建设和安全运行,其稳定处理措施是龙滩工程的重大关键技术问题之一。通过工程勘察设计阶段系统的研究,提出了边坡综合治理措施。目前边坡施工已经完成,监测资料表明,边坡是稳定的。
The high slope around the intake of Longtan hydropower station is a typical adverse bedded rocky one, 420 meters high at the most, joining to the tilting creeping natural slope at its upstream side. Nine big excavation water-intaking tunnels lie at its foot. It is interconnected with excavated slope of the diversion tunnel＇sintake, forming a high slope with complex outline. The stability of creeping slope and excavation slope is directly related to the successful construction and safe operation of the power station. How to cope with its stability problem is one of key great technical issues to Longtan project. Through systematic research at reconnaissance and design stage, comprehensive treating measures have been put forward. Presently the slope project has been completed. The monitoring data proves that the slope is stable.
