中文摘要: 隧道掘进机是我国当前急需重点研究的重大技术装备。由于缺乏刀盘拓扑结构设计理论及结构性能评价方法的指导,施工中经常出现机器参数、施工参数和岩土特性参数不匹配,并导致刀具、刀盘破损失效严重,整机故障率高、能耗大,掘进性能低下等问题。本项目拟应用粗糙集理论研究刀盘的拓扑结构特征及地质特征参数的提取和数学描述方法,识别决定掘进性能的多领域参数间的复杂耦合关联,建立描述掘进机性能的影响因素的数学模型。进而以掘进机掘进能耗、效率、稳定性等为指标,揭示不同地质特征下,不同拓扑结构的刀盘对掘进机性能的影响机理。应用非线性回归理论,建立刀盘拓扑结构性能耦合评价指标体系。在此基础之上,建立刀盘拓扑结构性能评价指标耦合计算方法及掘进机操作参数的设置与控制方法,形成全面的刀盘拓扑结构性能预测评价方法。最终通过室内试验和实际工程对研究成果进行验证与完善,建立一套刀盘结构性能评价理论,为刀盘设计和施工优化提供方法支撑

英文摘要: The Tunnel Boring Machine (TBM) is widely used in the world while lacking research in China. For the lack of mature instruction from the performance evaluation theory of the TBM's Cutter-head topological structure, the parameters of machine, the rock properties and the machine operation do not match well with each other, which leads to the excessive and abnormal wear of the cutting tools and cutter-head, the high failure and the more energy consumption of the machine and the lower efficiency in boring, etc. This project aims at extracting mathematical description of the parameters of the cutter-head topology structure and the ground condition with Rough Set Theory, distinguishing the sophisticated coupling association among the multi-area parameters which decides the performance of the TBM cutter-head, establishing the mathematical models which describe the TBM dynamic performance and revealing the influence mechanism from topological structure of the cutter-head on the TBM performance under different ground conditions. Then, the evaluation index system is established with non-linear regression method. On this foundation, the calculation method of the evaluation index and the regulation method of machine's operational parameters are established, which finally constitute an exhaustive prediction & evaluation meth
