水下盾构隧道力学行为的监测对于确保其长期结构稳定性至关重要。通常由经验或半经验方法确定的有限监测点和粗放监测方案,在捕获整个结构完整力学状态方面面临巨大挑战。本研究引入一种使用机器学习算法的整体结构应力分布空间推演模型,优化监测方案。

本文简介:

长期以来,水下盾构隧道的结构稳定性监测高度依赖经验法则,针对水下盾构隧道监测点位稀疏、结构全貌难捕捉的挑战,本研究提出了一种基于机器学习算法的隧道测点布设优化方案:通过对数值模拟数据集进行聚类分析,精准锁定结构力学响应的关键特征位点,实现从“经验布点”向“智能布点”的跨越;利用监督学习技术,以极少数典型位点数据驱动隧道全场力学信息重建,极大拓宽了结构感知边界。研究界定了衬砌结构的核心监测区与辅助布点策略,显著提升了对复杂环境下的结构表征能力。相比传统方案,本模型在保障监测精度的同时大幅降低了布设成本,为大型基础设施健康监测提供了精准、高效的决策支持。

02

本文亮点: 

  1. 从“经验驱动”转向“数据驱动”,实现监测方案的科学定量优化 

  2. 攻克“以点带面”推演难题,实现稀疏测点下的全场高保真重建 

  3. 强化“AI+工程”跨学科融合,为基础设施智能运维提供新范式

结论:

本研究结合聚类与线性回归算法,提出了一套隧道结构监测点优化布设方法:通过谱聚类确定关键特征位点,再利用回归模型实现从有限测点到整体截面应力分布的精准重建,有效解决了传感器数量有限与结构感知不足之间的矛盾。阐明了盾构隧道最优监测位点,界定了衬砌结构的核心监测区与辅助布点策略,同时揭示了“监测冗余”现象:测点并非越多越好,过量布点会导致信息冗余,反而削弱模型的表征精度与泛化能力。通过与多种常用模型的对比分析,并引入 RMSE、MAE 和 MAPE 等多项评价指标,证实了所提模型的优越性,在表征能力和可靠性上显著优于传统方法。该研究成果已成功应用于南京、武汉等长江隧道的实际监测中,为大型水下隧道的结构安全评估与防灾减灾提供了坚实的科学依据。

06

三个关键的未来研究方向(供领域学者学术传播与战略规划参考):

  1. 多源数据融合与深度学习模型优化:当前研究主要基于数值模拟数据,未来应融合实际监测数据、地质勘探数据、环境数据等多源信息,结合深度学习算法(如卷积神经网络、循环神经网络)进一步优化推演模型的准确性和鲁棒性。

  2. 实时动态监测与预警系统集成:建立实时数据传输与处理平台,将优化后的监测方案与智能预警系统深度集成,实现隧道结构状态的实时评估、异常识别和灾害预警,提升隧道运营的安全性和可靠性。

  3. 跨工程类型与多尺度监测方案推广:将该优化模型推广应用于不同类型的地下工程(如地铁隧道、矿山巷道、地下管廊等),并研究多尺度监测方案(从局部点到整体结构)的通用性,形成标准化的监测方案优化技术体系。
