本文讨论了单桩和复合地基静载荷试验的p—s曲线类型和影响因素，以及对应曲线情况下承载力的确定问题，对单桩，从桩土相互作用角度归纳了在垂直荷载作用下桩顶p—s曲线的特征；对复合地基，主要分析了搅拌使强度和均匀性对p—s曲线类型的影响。 This paper discusses the p-s curve types and influencing factors of the static load test of single piles and composite foundations, as well as the problem of determining the bearing capacity under the corresponding curves. For single piles, the piles are piled under vertical loads from the perspective of pile-soil interaction. The characteristics of the top p-s curve; for the composite foundation, the influence of the strength and uniformity of stirring on the p-s curve type is mainly analyzed.
