Research and Application of Balanced Rise of Concrete High Arch Dam
摘要
In the construction of domestic concrete high arch dams, there have been varying degrees of situations where the height difference between adjacent dam sections and the entire dam exceeds the design indicators. Due to the complex structure, large scale, high temperature control requirements for the dam body concrete, strict control requirements for the height difference between adjacent dam sections and the entire dam body, and complex boundary conditions, the rising speed of the bank slope dam section, non-orifice dam section, and orifice dam section is not consistent during the construction process, resulting in uneven rise of the dam concrete construction. In response to this situation, the resources need to be fully considered according to the simulated schedule of dam concrete construction. In this research, the finite element, PKPM and other software were used to study technical measures for rapid rise of the bank slope dam section and orifice dam section, and achieved the goal of balanced rise of the Baihetan concrete arch dam.
