潮汐作用下重力式沉箱压载致倾调平的试验研究

为避免沉箱在坐底时产生较大的倾斜,在受潮汐作用的条件下,针对在淤泥质海床上锚固定位后的沉箱进行压载致倾调平物理模型试验研究。试验中,根据地质勘察报告给出的现场分层地基的土层厚度及物理性质指标,将地基模型分成3层。通过本研究,分析总结沉箱在饱和软粘土地基上临近压载坐底前的过程,试验结果可为工程施工提供参考。

Test Research on Leveling Adjustment of Gravity Caisson from Ballast-induced Inclination under Action of Tide

In order to avoid the large inclination of the caissons when being placed on the muddy bed,the physical model test research on leveling adjustment of gravity caisson from ballast-induced inclination after being anchored and positioned was conducted.Based on the depth of the in-situ stratified foundation and the physical property index of soil given by the geologic exploration report,the model foundation was divided into three layers.The process of caissons before being placed on the saturated soft clay foun...
