(一)壩型的说明巨型水力枢纽挡水壩壩型的研究,具有特别重要的实际意义。合理地选择壩型,不仅可以节省巨额投资,而且可以缩短工期,加快建设速度。三峡水力枢纽在江流中心的壩段,由于不仅要布置大量的泄洪底孔,还要在壩顶溢流,这里采用重力式壩型是合理的。但是除了这个泄洪的壩段,两边还有很长的壩身,工程数量非常浩大,采用那种型式才能体现多、快、好、省的建设方针呢?
(A) Description of dam type Research on the dam type of giant hydraulic dam retaining dam has a particularly important practical significance. Reasonable choice of dam type, not only can save huge investment, but also can shorten the construction period and speed up the construction speed. Three Gorges Dam in the river dam center, due to not only to arrange a large number of flood discharge bottom hole, but also in the crest overflow, gravity dam here is reasonable. However, in addition to this flood discharging dam section, there are still very long dam bodies on both sides. The number of projects is very vast. Only the type of construction can reflect the principle of multi-purpose, quick, good and provincial construction?
