碾压混凝土坝最新发展

碾压混凝土坝最新发展(中文5400字,英文3200字)
摘要
经过十多年碾压混凝土坝平均体积没有增加的稳步发展期后，在过去的三年或四年碾压混凝土坝的体积迅速增加。现在不仅任何合理规模的重力坝的建造，而且弓形结构重力碾压混凝土坝，甚至拱形碾压混凝土水坝在施工方法上也有足够的信心。在越来越有信心的同时，保持碾压混凝土坝施工方法的简单和经济也会有一些事态发展。

LATEST DEVELOPMENTS IN RCC DAMS
ABSTRACT
 After ten years of steady development during which time the size of the average RCC dam did not increase, in the past three or four years the size of RCC dams has increased rapidly. There is now sufficient confidence in the method of construction for not only gravity dams of any reasonable size to be constructed, but also arch-gravity RCC dams and even arch'RCC dams. In parallel with this increasing confidence, there have been a number of developments that are maintaining the simplicity and economy of the RCC dam method construction.
