The construction process of tunnel groups is complex and the construction site is limited. Professional types during the construction vary and there is too much mutual interference of these types. There exist a lot of uncertainties and risk factors. The formulation of the construction schedule and the control of the implementation are complex. In order to improve the scientific and efficiency of schedule simulation of tunnel groups’ construction,a construction schedule simulation system based on drilling and blasting method which is used for assistant decision of establishing the schedule plan is designed. This simulation system is on the basis of system design and simulation theory of discrete system,and the CYCLONE model of the drilling and blasting construction is the center of the system. The functions of the simulation system include engineering data management,construction schedule simulation, network planning analysis, and statistical analysis,which have achieved the target functions of simulation and optimization of the construction schedule,construction schemes optimization and construction period optimization and so on. Accurate reference data and reasonable measures for the construction organization design and construction schedule control of tunnel groups are provided by this system. The application in Qiandao Lake water distribution project further validates the adaptability and universality of this system.
