However, the construction simulation studies of foreign focus on civil engineering, port engineering etc, while they are rare in hydropower engineering.
In the beginning of 80's, the construction simulation of hydropower engineering was led by Tianjin University in domestic, and numerous pioneering research results had achieved[6].
The controlling model corresponds to the basic units of the engineering control ——activities, which is the foundation of the construction progress, quality and cost control.
