摘　　要：文章提出了支持向量机模型对桩基极限承载能力进行预测的方法,结合自平衡法测试结果向静载试验的桩顶荷载-位移曲线转换方法,对桩基的沉降进行了预测分析。结果表明,采用该方法能够有效地预测桩基的承载能力和沉降情况,为高速铁路高架桥的设计、施工及运营提供了重要的理论依据和技术支持。In this paper,the support vector machine model is proposed to predict the ultimate bearing capacity of pile foundation,and the settlement of pile foundation is predicted and analyzed by combining the transformation method from the test results of self-balancing method to the load-displacement curve of pile top in static load test.The results show that this method can effectively predict the bearing capacity and settlement of pile foundation,which provides important theoretical basis and technical support for the design,construction and operation of high-speed railway viaduct.
