摘要
施工系统仿真方法是地下洞室群施工过程优化分析的有效手段。为了提高资源利用率并降低施工成本,地下洞室群不同施工工作面之间常共用施工资源。然而现有的施工仿真研究未能对施工资源在不同工作面之间的流转情况进行充分分析,进而影响仿真结果的准确性。针对上述问题,提出考虑施工资源共用的地下洞室群施工仿真方法。首先,从时间维度、空间维度、作业维度和组织维度方面对施工资源共用的多维约束进行分析;进一步,构建考虑施工资源共用的施工分层仿真模型,其中,将资源实体作为独立对象进行建模以逐一模拟其工作、闲置等状态,进而将施工资源对象模型并与CYCLONE模型耦合,实现对施工资源流动过程的准确描述和施工过程的精细化仿真模拟。工程实例表明,相比于传统仿真方法,考虑施工资源共用的仿真结果在工期和机械投入预测上都更贴近工程实际。
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.
