非稳定法用张力样条计算模型拟合P－S曲线
-
摘要: 本文分析了载荷试验数据处理的非稳定法高次多项式拟合不规则p-s曲线的局限性,论述了张力样条函数计算模型拟合不规则p-s曲线的可行性,借助工程实例说明该法为拟合p-s曲线的较好模型。Abstract: The restricts of the non-steady method with multinomial of higher degree to fit irregular curve of p-s in the data treatment of load test are analysed and the feasibility of the tensionspline calculative model to fit the irregular curve of p-s is discussed in this paper. It is shown that the better model to fit the curve of p-s by engineering practices.
