| 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. |
