一、混凝土坝合理化施工的必要性最近修筑的高坝,填筑坝比混凝土坝多,这是因为适合修建混凝土坝的地形和地质条件的坝址已经减少,这种坝址修建填筑坝往往比较有利。由于填筑坝能够就地取材,材料处理比较简便,且能用机械化施工,因而修建填筑坝比修混凝土坝经济;但填筑坝不能泄洪,也不能在坝体内设置混凝土结构物,为了保证防洪安全,其溢洪道过水断面要大于混凝土坝。此外,混凝土坝坝体的水密性和耐久性比较可靠,结构分析的精度较高,建成后,坝体几乎完全不产生变形,因而便于维修管理.混凝土坝合理化施工研究的目的,在于以混凝土坝之长,补填筑坝之短,改进混凝土坝 I. The Necessity of Rationalized Concrete Dam Construction Recently more high dam and filling dams are built than concrete dams because the dam sites suitable for the topography and geological conditions of concrete dams have been reduced. More favorable. Because filling dams can be made locally, materials are easy to handle and can be mechanized, the construction of dams is economically more efficient than rehabilitating dams; however, filling dams can not discharge flood waters and concrete structures can not be provided in dams Flood control safety, the spillway crossing section is greater than the concrete dam. In addition, the watertightness and durability of the concrete dam body is more reliable and the precision of the structural analysis is higher, and the dam body is almost not deformed after the completion, which is convenient for maintenance and management. The purpose of the rationalized construction of the concrete dam lies in that the concrete dam The length of fill filling dam short, improve the concrete dam
