| 摘 要： | 针对现有的平台无法实现盾构施工过程中多源信息的实时交互，造成施工关键信息沟通不畅而引发沉降过大的难题，以施工过程中盾构PLC掘进参数、隧道周边建（构）筑物情况、掘进土层信息和监测数据等多源信息为对象，开展多源数据的自动获取与时空融合方法的研究，开发基于移动互联的盾构掘进多源信息实时交互平台，使项目参与人员实时了解盾构施工情况并针对特定问题开展互动讨论，以解决盾构施工过程中信息沟通不畅的难题。通过在济南地铁R3线穿越老旧居民楼群的应用，实现了穿越施工地上地下数据联动，解决了盾构施工沉降控制过程中的协同管理难题，实现了既有老旧居民楼沉降控制在-5 mm以内的微沉降控制目标。

| Abstract: | The current platform cannot realize real time
interaction of multi source data generated during
shield tunneling, resulting in poor communication of crucial information and
overlarge settlement. Therefore, the automatic acquisition and integration
approach of multi source data are studied based on
shield PLC tunneling parameters, surrounding buildings, soil conditions and
monitoring data. And then an interaction platform of multi source data based on mobile application is developed to demonstrate
the tunneling information in real time for all the
participants. With this platform, problems encountered during the shield
tunneling can be solved by mobile interaction. The case study of shield
underpassing adjacent buildings in Jinan Metro Line 3 shows the effectiveness
of the real time interaction platform of multi source data, which realizes micro settlement control of -5 mm. |
