摘　　要：盾构隧道施工经常会穿越各类管线,对隧道工程本身及管线安全运行均会产生影响。以南宁地区某盾构隧道施工时下穿管道为背景,采用支持向量机回归算法建立管控模型,分析盾构施工参数与管线沉降之间的关系。结果表明,采用这一智能算法建立的模型经过训练后,管线沉降预测值与实际值吻合度较高,表明该模型具备稳定的预测能力和良好的泛化能力,对预测和管控施工风险、优化施工参数具有指导意义。During the construction of shield tunnels,crossing pipelines may have a certain impact on the safe operation of the tunnel and pipelines.The application of intelligent algorithms in the safety risk management of shield tunnel construction is explored,using the undercrossing of pipelines during the construction of a shield as a background.By analyzing the engineering geological conditions,shield construction parameters,and data related to the drainage pipelines,a management model is established using SVR algorithm,hoping to improve the safety of underground pipelines in shield tunnel construction and provide a reference for similar projects.
