摘要
通过概述单桩竖向抗压承载力产生及确定的方法及过程,系统地分析总结了单桩承载力标准值、特征值、设计值、基本值及极限标准值等名词术语的来龙去脉及传承,理清了彼此之间的复杂关系,阐明了这些名词术语的概念及在相关规范中的取舍原因。得到的结论有:可暂停使用"桩端阻力特征值"及"桩侧阻力特征值"名词;以后时机成熟时,可恢复使用单桩承载力"设计值"及"基本值"名词,"特征值"可修改为"设计值","极限标准值"名词可去除"极限"两字;基础规范及桩基规范用于计算单桩承载力的公式从概念的角度理解,可认为理论上都存在着不完善之处,后者相对更直接、更可靠一些。
By outlining the production methods and determination processes of compressive bearing capacity of single pile, we systematically summarize the history and inheritance relationships between the nouns and terms such as standard value, characteristic value, design value, basic value and ultimate standard value of bearing capacity of single pile, clarify the concepts and naming reasons of these nouns and terms in codes, make the complex relation- ship between each other clear. The conclusions show that the nouns of pile shaft resistance characteristic value and pile tip resistance characteristic value may be suspended temporarily; when the time is right, the nouns of ＂ basic value＂ and ＂ design value＂ of bearing capacity could be used again, and the bearing capacity characteristic value could be modified to bearing capacity design value, in addition, the word ultimate could be wiped from the noun of ultimate standard value. Moreover, there are some theoretical disadvantages of formulas for calculating the bearing capacity of single pile in the foundation code and pile code, the latter is relatively more direct and more reliable.
