| 摘 要： | 介绍地铁车站桩柱合一体系的超长中桩柱的静载试验方法，并根据试验结果，分别采用灰色理论的非等步长GM（1，1）模型和三维拉格朗日元的数值模拟方法，进行桩基沉降的对比预测，结果表明两种预测方法相互印证，桩基设计安全合理，为桩基的优化设计提供了依据，也为地铁超长柱基体系的研究提供了参考。

| Abstract: | This paper introduced a method of static load test for a king pile in a pile-pillar system in subway station. Based on the data from the test,both grey theory and numerical simulation were used in the forecast for the carrying capacity of the pile. Results showed that these two methods of forecast testified each other and the testing pile satisfied design requirements. Some consulting opinions and suggestions were proposed in this paper. |
