摘要
大型管道工程一直都是城市的生命线工程,针对大型管道工程的健康监测问题一直都是研究的热点。该文结合“数字孪生”技术和超大口径柔性玻璃钢夹砂管道在不稳定滩涂地质区域施工应用的案例,研发了一套基于物联网系统和虚拟仿真模拟技术的全天候自动化管道安全监测技术体系,该技术体系通过对有限的传感器数据与数字孪生技术相结合,可实现对管道工程全局安全状态的实时监测分析。该文详细介绍了该监测体系的基本工作原理、组成架构、搭建实施过程和监测效果评价等情况。实际工程应用效果表明:该监测体系通过将各类传感器数据与仿真计算模型相结合,可实时、自动分析计算管道在施工和正常运行期间的内力和变形情况,有效反应管道的内力、形变和沉降等基本安全状态;在地质不稳定的滩涂区建设超大口径柔性管道工程,管槽的基础形式对于管道后续的受力和变形情况至关重要。
Large-scale pipeline projects have always been crucial lifeline projects for cities,and the health monitoring of such projects has been a research hotspot.Thusly,this study combines the"digital twin"technology with the case of construction application of ultra-large-diameter flexible glass fiber reinforced plastic(GRP)sandfilled pipelines in unstable tidal flat geological areas.It develops a comprehensive and automated pipeline safety monitoring technology system based on the Internet of Things(IoT)system and on virtual simulation technology.This technology system combines limited sensor data with digital twin technology to achieve real-time monitoring and analysis of the overall safety status of pipeline projects.The paper provides a detailed introduction to the basic working principles,composition architecture,implementation process,and evaluation of monitoring effects of this monitoring system.The practical application of this system demonstrates that:by integrating various types of sensor data with simulation calculation models,the monitoring system can analyze and calculate the internal forces and deformations of the pipeline in real-time during construction and normal operation.It effectively reflects the basic safety states of internal forces,of deformations and,of settlements of the pipeline.In the construction of ultra-large-diameter flexible pipeline projects in geologically unstable tidal flat areas,the foundation form of the pipeline trench is crucial for subsequent stress and deformation conditions of the pipeline.
