摘　　要：隧道围岩变形影响到隧道施工的安全,对隧道围岩变形进行预测,可作为指导隧道施工的依据。以江西某隧道围岩变形问题为研究对象,采用在小样本、非线性、高维模式识别问题中具有优势支持向量机理论建立模型,建立隧道围岩变形预测模型,结果显示,实测值与预测值相差很小,证明此方法有很强的实用性。The deformation of the surrounding rock of the tunnel affects the safety of the tunnel construction,and predicts the deformation of the surrounding rock of the tunnel,which can be used as a basis for guiding the tunnel construction. In this paper,a tunnel in Jiangxi is used to establish a model with the advantage of support vector machine theory in small sample,nonlinear and high-dimensional pattern recognition problems to predict the deformation of tunnel surrounding rock. The prediction results show that the measured value and the predicted value are very small,proof this method is very practical.
