结合工程实际探讨了围护灌注桩部分混凝土凿除后的抗弯承载力性状。首先通过概念分析,确定灌注桩混凝土凿除对承载力的影响因素;其次,采用数值分析的手段,确定灌注桩混凝土部分凿除后的抗弯承载力;最后,建立三维有限元模型,模拟各个施工阶段混凝土凿除后灌注桩工作状态时的弯矩分布。计算结果和实践均表明文中提出实施方案可行。
Combined with engineering practice, the flexural capacity of perforated concrete piles after partial chipping is discussed. Firstly, through the conceptual analysis, the influencing factors of the bearing capacity of concrete pouring pile concrete are determined. Secondly, the numerical analysis method is used to determine the flexural capacity of concrete after partial excavation. Finally, a three-dimensional finite element model is established to simulate Distribution of moment in concrete working condition after concrete chiseling. The calculation results and practice indicate that the proposed scheme is feasible.
