洪秀全水库溢洪道橡胶坝的重建设计

Reconstruction designing for the spillway rubber dam in Hongxiuquan reservoir

阐述了洪秀全水库溢洪道橡胶坝在重建设计中,通过H1=2.4m双线锚固坝袋综合指标的分析,同时考虑控制段底板最大最小应力比控制,从底板长度出发,采用内外压力比为1.3的设计选择。文章还介绍了坝袋结构型式做堵头式橡胶坝的改进和底板适应性的改进设计。

This paper expounds the analysis for synthetical indexes of anchoring rubber dam using double line through H1=2. 4m, meanwhile controling the ratio of maximum stress to minimum according to the length of bottom board and the ratio 1. 3 of internal presure and external. It also in- troduces the rubber dam design and bottom board adaptability design improved.
