摘　　要：马槽河水电站拦河大坝是一座外掺MgO不分横缝的拱坝,在施工图阶段通过对坝址地质条件深入细致的研究,将初步设计阶段的抛物线拱圈优化为统一二次曲线形拱圈的双曲拱坝,在使坝体应力水平及坝肩抗滑稳定满足要求的前提下,节省了坝基开挖及坝体混凝土工程量;同时采用MgO筑坝技术,降低了施工难度,使得电站提前发电。获得了良好的经济效益及社会效益。The Macao River hydropower dam is an additive MgO style arch dam without joints.Researchers optimized the parabolic arch ring which had been designed at preliminary stage into unified quadratic curve-arch ring of double curved arch dam by intensive research on the geological conditions during the stage of construction.Under the premise of meeting the requirements of the dam stress level and the abutment's anti-sliding stability,constructors saved much project of dam foundation's excavation and dam concrete.At the same time,researchers adopted MgO Dam's construction technology,reducing the difficult in construction and made the power generation in advance which had an economic efficiency and social efficiency.
