洪家渡水电站进水口顺向坡加固处理设计

经过对洪家渡水电站进水口顺向坡稳定问题的系统分析研究，采用了以大型抗滑桩与锚索联合加固并辅以排水的处理方案，通过对抗滑桩、锚索及施工支洞的合理布置与设计，成功地解决了进水口顺向坡处理技术难度大、施工干扰大和工期紧的难题。目前，洪家渡水电站进水口顺向坡锚索及抗滑桩施工已顺利完成，并已经受了下闸蓄水和发电运行的初步考验，监测情况表明，稳定状况良好。

Strengthening Design For Inlet Consequent Slope Of Hongjiadu Hydropower Station

The treatment of inlet consequent slope of Hongjiadu Hydropower Station had some technology difficulties, construction disturbance and short construction period. On the base of systematically researching its stability, the treatment scheme using large-scale piles against sliding and anchor cables for strengthening as well as drainage measure was adopted. As a result of reasonable layout and design of piles against sliding, anchor cables and construction branch tunnels, the problem of treatment consequent slope was successfully solved. After impounding and short operation of the units, supervision result has made known that its stability is fine.
