CONCULUSION In this paper, according to the collision problem in high arch dam construction process, the model of time-space evolution model for entities in the storehouse is establish first. Then, the type and effect of the collision are analyze and the collision detection and adjustment mechanism was established. At the same time, a dynamic adjustment and optimization model of the construction scheme was established. At last, a case study is carry out according to a real practice, and the results shows that the method proposed in this paper can effectively provide a scientific basis for decision-making of construction projects. 802
