摘要 基于p-y曲线法和比例系数,对双排桩侧向位移进行计算,考虑了桩土接触的非线性,并结合有限单元法进行验证.研究表明:采用p-y曲线法计算门式双排桩侧向位移,在位移曲线的形态及数值上十分接近真实情况,采用p-y曲线法的非线性分析对双排桩的水平位移计算是十分合理的,对实际工程中快速计算双排桩位移具有指导意义. The deformation and displacement of double-row pile are studied based on the p-y curve method,combining actual engineering cases and finite element method.The result shows that the lateral displacement of the double-row piles calculated by the p-y curve method is very close to the real situation in the shape and value of the displacement curve.The nonlinear analysis of the double-row piles by the p-y curve method is very rational.It has guiding significance for the rapid calculation to the displacement of double-row piles in actual engineering.
