利用1996年1月和1997年1、2月份的观测责料对海冰相对于沉箱的爬升和堆积模式进行了校验研究。主要结果如下:(1)沉箱海冰爬升的主要贡献,来源于海冰所具有的动能和潮汐运动时引起的海平面抬升。海冰爬高与潮汐引起的海面高度变化成正比,与海冰初速的0.5次方成正比。(2)通过对几次观测资料的分析发现,在渤海海域,当海冰厚度小于10 cm时,海冰不发生相对于沉箱的爬升和堆积。(3)在渤海海域,随海流和风速的大小和方向的变化,海冰运动的方向可以达到任何方位,故此海冰能够在沉箱的任何方向上产生爬升,从而在该方向上产生堆积。(4)据观测和计算,海冰在沉箱上的堆积具有自身屏蔽作用,即海冰通常只堆积在沉箱的四周。
Using the observation accords of January 1996 and January and February 1997, the calibration of sea ice versus caissons was studied. The main results are as follows: (1) The main contribution of sea ice climbing in caissons comes from the sea level rise caused by the kinetic energy and tidal movement of sea ice. Sea ice climb is directly proportional to the sea surface height caused by the tide and is proportional to the 0.5th power of the sea ice initial velocity. (2) Through the analysis of several observation data, it is found that in the Bohai Sea, when the thickness of sea ice is less than 10 cm, sea ice does not climb and accumulate relative to caissons. (3) In the Bohai Sea, sea ice moves in any direction with changes in the size and direction of currents and wind speeds, so that sea ice can climb in any direction in the caisson and build up in this direction. (4) According to observation and calculation, the accumulation of sea ice in the caisson has its own shielding effect, ie sea ice usually only accumulates around the caisson.
