用双曲线模拟载荷试验曲线方法探讨

Discussion on the curve fitting method for PLT with hyperbola

摘要: 建议用双曲线模拟载荷试验曲线，易于建立地基破坏标准，求得地基基床系数及其内在关系。在此基础上提出用极限承载力或静力触探指标估算割线基床系数的经验公式。

Abstract: It is proposed that PLT curve is fitted by hyperbola in this paper.On the curve,it is easy to establish the failure standard ,then the coefficient of subgrade and the internal relation can be obtained,and an empirical formula,which estimates the secant coefficient of subgrade from ultimate bearing capacity or CPT parameter,is suggested
