Abstract：In order to prevent the collision between several interference tower cranes in the same construction site， the collision model of the same height and different height tower cranes was firstly established. On the basis of the traditional tower cranes anticollision algorithm， the intelligent collision avoidance algorithm was presented， which used the shortest waiting time method on the same height tower cranes and used the latest intervention method on the different height tower cranes. Finally， the realization of the intelligent collision avoidance algorithm was given. The research results show that this intelligent collision avoidance algorithm can significantly reduce the tower cranes’ waiting time and effectively improve the construction efficiency.
