摘　　要：针对桩基水平承载力计算的2种方法——m法和p-y曲线法,运用2个工程实例计算结果,进行了2种桩基水平承载力的计算方法对比分析。结合舟山与大陆联网大跨越工程,分析了各种因素对桩基水平承载力及变形的影响;为了优化承台厚度,计算时考虑了承台与群桩的共同作用。Both m method and p-y method are used to study the lateral bearing capacity of pile foundations. The comparisons between two methods are performed combined with the engineering practice. Based on Zhoushan-Mainland largecrossing project, the effects on lateral bearing capacity and distortation of pile foundations are analyzed. To optimize the thickness of pile cap, pile cap and pile group interaction is considered.
