摘要: 以使用5年以上的高桩码头的大管桩为研究对象,采用模型实验的方法对大 管桩的不均匀沉降进行了系统研究. 首先通过量纲分析,确定模型实验的各个物理量和相关 参数,以及模型材料(PVC管)等; 然后利用电测技术,经过大量实验,获得大管桩的不均 匀沉降量和变化规律; 同时,利用数值模拟,分析了大管桩不均匀沉降变化规律,验 证了模型实验结果的可靠性, 说明了利用数值模拟方法分析大管桩不均匀沉降是可行的.

Abstract: A high-piled wharf in use for more five years are studied with model experiment to obtain the uneven settlement of large-diameter concrete pipes. First, physical parameters for the model (PVC piles) are chosen through dimensional analysis, and then, the uneven settlement of the large-diameter concrete pipe is obtained by electrical measurement technology. At the same time, a numerical simulation is carried out to validate the model experiment results. It is shown that it is feasible to analyze the uneven settlement of the large-diameter concrete pipe with a numerical simulation.
