摘　　要：针对深层地基加固施工过程中数字化程度低、地下作业不可见以及工期不可控的问题,将数字孪生技术引入深层地基加固施工场景中,设计深层地基加固施工数字孪生系统.该系统结合地基加固区域的地质条件和监控需求,通过模型建立、数据采集与处理以及动态映射完成开发.模型建立阶段以多维度数据为基础,构建施工过程的数字孪生模型;数据采集与处理阶段通过传感器网络获取实时数据,并对数据进行校正与整合;动态映射阶段将施工数据与模型同步映射,实现地基加固施工过程的全方位数字化监控.将该系统成功应用于张靖皋长江大桥北航道桥南锚碇深层地基加固工程.应用结果显示,工程参数全部符合设计要求,其中部分参数远超设计预期,显著提升了施工效率和质量,解决了传统施工中地下作业不可见的问题.通过对工程参数的实时监控与动态调整,缩短工期,提高深层地基加固施工的可靠性与可控性,全面提升工程项目的数字化水平.Digital twin technology was applied to address issues of low digitalization,invisibility of underground operations,and uncontrollable schedules in deep foundation reinforcement.A digital twin system was designed based on geological conditions and monitoring requirements.The system was developed through model establishment,data acquisition,and dynamic mapping.In the model establishment stage,a digital twin model of the construction process was constructed based on multi-dimensional data.In the data acquisition and processing stage,real-time data was obtained through a sensor network,and then corrected and integrated.In the dynamic mapping stage,construction data and the model were synchronously mapped to achieve all-round digital monitoring of the foundation reinforcement construction process.The system was applied to the south anchorage of the Zhang jing-gao Yangtze River Bridge’s north channel bridge.Results showed that all engineering parameters met or exceeded design requirements.Efficiency and quality were improved,and underground operations were visualized.Through real-time monitoring and dynamic adjustment of engineering parameters,the construction period was shortened,the reliability and controllability of deep foundation reinforcement construction were improved,and the digital level of the engineering project was comprehensively enhanced.
