A Study on construction simulation of underground cavern groups with a focus on resource sharing in construction

Abstract

Construction system simulation method serve as effective tools for optimizing the analysis of underground cavern group construction processes. To enhance resource utilization and reduce construction costs, “Resource Sharing in Construction” is routinely practiced across various workfaces of underground caverns. However, existing construction simulation studies fail to thoroughly analyze the transfer of construction resources between different workfaces, subsequently affecting the accuracy of the simulation outcomes. Addressing this issue, this study proposes a construction simulation method for underground cavern groups that incorporates resource sharing. The approach starts by analyzing multi-dimensional constraints on resource sharing from temporal, spatial, operational, and organizational perspectives. Further, a tiered construction simulation model is developed, which models resource entities as independent objects to simulate their active and idle states individually. These resource objects are then integrated with the CYCLONE model, enabling precise descriptions of resource flow and detailed simulation of the construction process. Engineering case studies demonstrate that, compared to traditional simulation method, the simulation result incorporating resource sharing provide more accurate predictions of construction timelines and machinery deployment, aligning closely with real-world engineering conditions.
