各种桩基的不完整型P -s曲线可用以P为自变量的普通指数函数模型描述 ,单桩的完整型P -s曲线则可用以s为自变量的各种形式的函数模型描述 ,以幂函数模型具代表性。该文推导了P -s曲线模型的曲率极值的数学模式 ,分析了这些模式间的关系和适用性
The incomplete P-s curves of various pile foundations can be described by ordinary exponential function models with P as independent variables, and the complete P-s curves of single piles can be described by various forms of function models with s as independent variables. The power function model is representative. This paper deduces the mathematical model of the curvature extremum of the P-s curve model, and analyzes the relationship and applicability of these models.
