关于高桩码头中长桩内力计算方法的探讨

摘要

As for inelastic long pile wharf, fixing point method and m-method are adopted to calculate the internal force of foundation piles respectively, which is limited by site geological conditions. By comparing and analyzing the internal force calculation result of foundation piles, it is found that the above two methods deduce similar axial force of foundation piles, but different moments of pile body. m-method simulates the external force of real foundation soil on foundation piles well, and the calculation result of internal force is more reasonable. Therefore,it is proposed to apply m-method in the internal force calculation of medium length piles.%针对受实际工程地质条件所限的非弹性长桩码头基桩，采用嵌固点法和“m法”分别计算基桩的内力。根据对基桩内力计算结果的对比分析，通过上述2种方法计算所得的基桩轴力差别不大，但桩身弯矩却差别明显。鉴于“m法”能够近似模拟真实地基土层对基桩的外力作用，内力计算结果比较合理，因此在中长桩的内力计算中建议采用“m法”。
