| 摘 要： | 通过物理模型试验,在淤泥质海床上沉箱锚定固位后受波浪、潮流作用的条件下,对沉箱坐底运动状态的稳定性和锚链最大拉力进行了试验研究.试验中考虑了受潮位影响时,沉箱与波浪、水流之间的相互作用关系,并实时记录了沉箱的运动状态.根据试验数据分析,得出在波浪、水流作用时沉箱坐底前后的运动现象与规律,总结了沉箱前锚链的拉力经验公式.试验结果为沉箱注水的工程操作过程提供了参考依据.

| Abstract: | Based on the physical model test,the caissons anchored and positioned on muddy sea bed were exposed to wave and tidal current,the stability of motion state and maximum anchor forces at the caisson bedding were researched.The effect of tidal level and the interaction between caissons and wave and current were both considered,and real-time motion state of caissons was recorded in the test.According to the test analysis,the motion phenomenon and laws of caissons bedding were obtained,and the empirical formula was derived.The results are referable to some practical engineering of water filling caisson. |
