蒲圻水利枢纽主坝是采取装配式砼坝设计的。主要优点是:1.加速施工进度:当采用块体尺寸为2.54×1.84×0.9公尺时,每月平均大坝上升速度为15～20公尺。2.提高质量:质量包括两个方面,首先大坝砼采用工厂化生产的干硬性砼,胶结后其强度比整体砼更好,其次不因砼中水泥水化热所产生的温度应力来破坏块体。3.节约投资,提早发挥枢纽效益:依初步成果分析,装配部分可节约水泥6.5%左右,并有可能更大的节约水泥用量(现正在进一步研究)。又因施工速度快,使枢纽效益及早发挥并可能减少施工导流的困难和投资。 The main dam of the Beishuang Water Conservancy Project is designed as an assembly type concrete dam. The main advantages are: 1. Accelerate the construction progress: When using block size of 2.54 × 1.84 × 0.9 meters, the average monthly dam rise rate of 15 to 20 meters. 2. To improve the quality: quality, including two aspects, first of all, the dam concrete factory production of hard and rigid concrete, the strength of the cemented better than the whole concrete, followed by concrete hydration heat generated by the thermal stress to destroy Block. 3. Save investment, take advantage of the hub earlier: According to the preliminary results, the assembly part can save about 6.5% of cement, and may save more cement (further research is underway). Due to the high construction speed, the pivotal benefit can be exerted as early as possible and the difficulties and investment in construction diversion may be reduced.
