一、引言碾压混凝土坝(RCC),最初被认为集中了混凝土坝(用抗冲蚀材料建造,断面小)和填筑坝(机械设备使用程度高,快速施工法)两者的主要优点。到了60年代的末期,普通混凝土坝就不如填筑坝经济,尤其不如堆石坝经济。混凝土坝由于大力采取措施克服诸如由混凝土水化热所造成的各种问题而变得更加复杂,但填筑坝的施工却因有了大型施工设备和对建筑材 I. INTRODUCTION RCC is initially considered to have focused on the major advantages of both concrete dams (constructed of erosion resistant materials, small cross sections) and filling dams (high levels of mechanical equipment use and rapid construction methods). By the late 1960s, ordinary concrete dams were not as economical as filling dams, especially as rockfill dams were economical. Concrete dams have become more sophisticated as a result of vigorous efforts to overcome various problems such as those caused by concrete hydration heat, but the construction of filling dams has been characterized by large-scale construction equipment and construction materials
