Study on Construction System Simulation and Schedule for Large-scale Underground Structure Group

The large-scale underground structure group construction is an extremely complicated process. In this paper, the construction process of large-scale underground structure group has been studied systematically. A new method on construction system analysis for large-scale underground structure group, which combines cyclic operation network, network plan and optimum, visual resource-oriented modeling technique and animation demonstration technique based-on GIS, is introduced. The approach described in this paper provides a quantitative analyzing tool for choosing the reasonable construction organization, obtaining the optimum equipment set plan, compiling the construction schedule, and grasping the construction processes. Moreover, the software of construction system simulation and schedule for underground structure group (ESAS) has been developed by authors, which is applied successfully to the construction organization and design of Xiluodu project.
