Abstract:
Over the past four decades, significant advances have been achieved in material science and construction technologies for the construction of dams. Among these, MgO concrete, rock-filled concrete, and roller-compacted concrete have been applied on an increasing trend in the construction of concrete dams. The application of these innovative materials and technologies in arch dam construction makes it possible to omit transverse and longitudinal contraction joints, which can speed up construction progress and reduce project costs. This paper discusses the design and construction features of arch dams constructed without contraction joints, highlighting the role of innovative materialsand associated construction methods.
