摘要：
本发明涉及一种基于最小二乘支持向量机的施工引起地表变形的预测方法，包括如下工艺步骤：(1)收集盾构施工引起的地表变形预测所需样本数据；(2)建立训练样本集和测试样本集；(3)建立基于最小二乘支持向量基的地表变形预测模型；(4)输入地层参数和盾构掘进工作参数，进行地表变形预测。本发明所述地表变形预测方法，通过少量样本数据实现可考虑盾构掘进参数影响的地表变形智能预测，计算成本低、效率高，适用于样本数据较少的新建盾构隧道施工引起的地表变形的快速预测。
摘要（英）：

The invention relates to a prediction method of surface deformation due to construction based on a least square support vector machine. The prediction method includes the following processing steps: (1), collecting surface deformation sample data needed for prediction due to shield construction; (2), building a training sample set and a testing sample set; (3), building a surface deformation prediction model based on the least square support vector; and (4), inputting the stratum parameter and the shield tunneling working parameter and conducting surface deformation prediction. The prediction method of surface deformation realizes surface deformation intelligent prediction which can consider the shield tunneling parameters through little sample data, and is low in calculation cost, high in efficiency and applicable to rapid prediction of the surface deformation due to new-building shield tunnel construction with little sample data.
