Study on continuous construction of Jinghong hydropower station RCC dam in high temperature;

The continuous construction of the Basecourse and the surface of the Lime-fly-ash Macadam is a new method that can accelerate the overall construction process, shorten the time limit for the project and further develop new characteristics of the Lime-fly-ash material.

Using cement hydration mechanism and gradation composition principle,design methods of anti-cracks base were put forward with expansive cement and skeleton and dense structure gradation;technologies of continuous construction of two layers and saw cracks in advance were used.
