五强溪水电站左岸高边坡观测及锚洞内部观测资料分析

五强溪水电站坝址左岸边坡高，自然边坡上缓下陡，边坡岩体岩性软硬相间，节理裂隙密集，从动土开挖之日起京开始了外部监测及锚洞内部观测，并对各种观测仪器量测的数据进行了精确的计算分析，从而对锚洞在高边坡处理中发挥的作用进行了定性评价。

Analysis of the results from outside deformation observation and internal anchorage tunnel observation in the high side-slope in the left bank or Wuqiangxi Hydropower Station

In the damsite of Wuqiangxi Hydropower Station, there is a high side-slope in left bank. The natural slope is gentle in the upper and steep in the lower. The rock body in the side-slope is hard alternating with soft and has intensive fissures. Since the commencement of excavation, the outside monitoring and internal anchorage tunnel observation have been conducted. The accurate computation and analysis on results from various measurement devices have been made. Therefore, the qualitative evaluation of the role of anchorage tunnel in the treatment of high sideslope has been completed.
