填土地基中桩侧负摩阻力计算方法

A Calculation Method of the Negative Skin Friction of Pile Shaft

就桩侧负摩阻力的计算方法进行探讨,介绍了桩侧负摩阻力的确定方法、中性点位置的确定及桩基承载力的验算,提出了相应的计算方法。同时通过工程实例对桩侧负摩阻力进行验算,说明了考虑桩侧负摩阻力在建筑工程中的重要性。

Based on national technical code for building pile foundations, when Idle paining through loose earth - filling and entering hard layer, negative friction should be considered. This paper diacusses a calculation method of the negative skin friction of pile shaft, and check pile bearing capacity through actual eases.
