【摘要】 那读水电站拦河坝采用浆砌石实体重力坝坝型,溢流坝布置在河床中部,为开敞式溢流,并采用挑流与面流相结合的阶段性消能。通过多次模型试验验证和优化原设计,重点解决消能防冲这一中心课题,使该坝的设计基本达到安全经济的效果。更多还原

【Abstract】 The Nadu hydropower station big dam applied grouted rubble gravity dam type, the overflow dam was open spillway, which been laid out in the middle of river bed, used step dissipation format combining deflecting with surface flow. By proving and optimizing the original design with several model test, the dissipation and scouring problems were solved, the dam design realized safety and economy.更多还原
