成果3：桥梁网级智能评估技术
孙利民团队提出了系统的桥梁网级评估理论、方法、技术，首先提出了一种自然退化的病害数据重构方法和基于自然语言处理技术的文本错误清洗方法，并基于检测报告中的病害数据提出两个基于病害严重程度的桥梁部件退化指标，随后集成病害指标、桥梁的基本结构信息和交通流数据建立路网桥梁多源信息数据库，最后基于自动机器学习建立并训练了了路网级的桥梁退化模型，实现对路网桥梁技术状况的准确预测。研究的主要创新点有：（1）目前在土木工程领域较少有人对桥梁非结构化文本数据进行研究，也罕见以桥梁检测报告为主体的数据清洗研究。本课题利用自然语言处理技术和深度学习等手段提取非结构化检测数据、定位并重构检测数据的残缺和错误数据，提高桥梁检测数据利用效率，为网级评估模型提供高质量的桥梁历史健康数据。（2）目前的桥梁评估模型都以评分和评级为量化手段，而评分、评级数据受检测人员主观影响大且不容易量化维修的影响。本课题基于桥梁定期检查得到的病害数据，提出两项衡量部件性能退化的技术状况指标，规避了技术状况评分受主观影响大的缺陷，同时实现对维修行为的量化。（3）目前对桥梁的评估和性能预测主要局限于单体桥梁级别，以区域桥梁为主体的桥梁退化模型也局限于神经网络，应用较少且需要大量参数调整。本课题基于自动机器学习框架将区域关键特征与结构状态进行关联，训练了两层的桥梁群退化模型，充分利用区域多源数据蕴含的桥梁退化信息，在较少的参数调整工作下，实现对区域全部桥梁（包含未有检测信息的桥梁）的状态评估与预测，并指导区域桥梁管养方案的制定。

成果2：基础设施性态智能预测
在基础设施建设和正常运营阶段，对基础设施关键性态进行监测和预测并在严重变形时发出预警，防患于未然，是具有重要工程意义的工作。同济大学团队基于广州地铁在建项目大规模性态监测数据，建立了针对在建车站基坑及支护变形的智能预测框架及多通道多步预测模型。首先采用分步聚类方法，用层次聚类对监测物理量进行聚类，之后基于监测点空间分布特征和监测数据时间维度上的相似性，使用K-means对测点进行时空聚类。然后，建立基于经验模态分解（EMD）和长短期记忆神经网络（LSTM)的集成模型，并进一步构建基于分步聚类（Stepwise clustering）和Transformer的多通道多步预测模型，通过将数据重组成多维时间序列输入神经网络模型，得到多测点未来多步预测值。该方法有效挖掘监测数据特征，并且利用多测点信息进行联合预测，可实现多测点未来多步变形的准确预测。
