单桩竖向承载力计算方法的改进

Improvement for the Calculating Method of Single Pile Erect Bearing Capacity

为解决利用不完整试桩结果直接求解单桩极限承载力所存在的资料不足问题 ,依据一般P s曲线所具有的特征和可延长性 ,通过对曲线延长替代式曲率函数的建立 ,采用数学求极值的方法 ,获得了可直接完成单桩竖向极限承载力的计算公式 ,经实例计算分析比较 ,该方法计算过程简捷直观 ,精度可靠 ,具有一定的实用价值。

According to the character and extensibility of the ordinary P?s curve,through Prolonging the curve and creating a substitute curvature function,geting a calculating fermula of single pile's ultimate bearing capacity by mathematic method.On the basis of analyzition and comparation,this formula's feasibility is proved.
