【摘要】 半圆形构件是港口工程中新型构件。通过冰力模型试验 ,研究了作用在构件上的水平冰力和竖向冰力 ,试验工况包括不同水深和不同冰速 ,论述了构件内部存水冻结的可能性 ,分析了冰层温度场。采用层合板理论对冰层做了热弹性有限元的分析和计算 ,给出了冰层宽度最大的第一层冰的温度膨胀力。最后对于这种新型构件在渤海湾一带港口工程中的适用性提出了看法。更多还原

【Abstract】 Semi-circular concrete members are a new type of structural members used for harbour engineering.By means of ice force model tests with different working conditions such as different water depths and ice velocities,the horizontal and vertical ice forces acting on the members were studied.The possibility of freezing inside the members is expounded and the temperature field in ice layers is analyzed.Ice layers are calculated and analyzed with the thermo-elastic finite element method in accordance with the laminated layer theory and the thermal expansive force of the first ice layer with the largest width is thus given.Views on the applicability of this new type of structural members to the harbour engineering around the Bohai Bay are also given.更多还原
