白水水库基本完建蓄水后出现险情 ,大坝应力超过规范标准 ,坝顶溢洪道泄洪能力不足 ,右坝肩基面和山体大量渗水 ,局部失稳 ,左坝头 6 3m高拱端悬空无支承。加固设计采用固结与防渗灌浆结合的方法处理坝基 ,加高大坝 2 2m ,增加调洪库容和溢洪道泄洪断面 ,同时局部加厚坝体 ,以满足泄洪和坝体应力要求 ,并在右坝肩设排水孔 ,左坝肩设置推力墩 Baishuihu reservoir basically completed after construction of water danger, the dam stress exceeds the standard, the spillway overflow spillway capacity is insufficient, a large basement of the right abutment and mountain water seepage, partial instability, the left arch dam 6 3m high arch d Support. Reinforcement design Consolidation and seepage grouting method combined with the treatment of dam foundation, increase the dam 2 2m, flood control capacity and flood spillway flood section increases, while local thickening of the dam to meet the flood discharge and dam stress requirements, and in the right dam Drainage set shoulder, left abutment set thrust pier
