摘要
文章根据最小曲率半径定义和中值定理,通过极值分析方法来确定桩基极限荷载。支承桩的桩身摩擦力和桩尖阻力的大小与入土深度及桩身、桩尖处土层的相对刚度密切相关。从某种意义上,可引用结构力学的固端弯矩分配系数概念,按它们的相对刚度分配。经实测资料验证,文中图解分析法准确、可靠。
Abstract Based on the minimum curvature radius definition and mid value theorem, the pape gives the method of determining the limit load of pile foundation through extreme value analysis.The value of frictional force of soil to pile body and resistance to pile toe has a close relation with the penetration depth and relative rigidity of soil layer at pile body and pile toe. In a sense,fixed ends bending moment distribution coefficient concept may be drawn.It is verified by real measured data that this method is accurate and reliable.
