摘要
为了探讨影响灌注桩承载力的因素,给出了灌注桩承载力计算的理论公式,分析了常用的施工工艺条件下灌注桩的承载力的计算考虑因素.通过3根试桩资料的结果与考虑各种影响因素的计算结果对比,验证了施工工艺的影响,并与有限元法计算结果进行了对比.结果表明,采用有限元方法与理论计算方法一样,必须考虑不同施工条件所造成的桩侧和桩端的特征,才能得到符合实际的承载力值.
Researches on the affecting factor of bearing resistance of filling calculating ultimate bearing resistance is put forward. This formula can take pile. The theoretical formula of into account these factors of construction conditions of different pored method. Test results including three piles are offered and compared with those of the theoretical formula and FEM. From these results we can conclude that it must take the construction technics into account to define the pile＇s bearing the bottom conditions are different. The results also capacity. Because the interface between pile and soil and confirm the viewpoint of this article.
