| 摘 要： | 国内外尚无人对冰力掩蔽效应进行专门研究。通过低温冰工程实验室内的冰力模型试验，研究了多桩柱结构在不同位置时桩柱间对冰力的掩蔽效应，探索了冰力掩蔽效应的机理和规律，得到了不同冰厚、不同桩柱直径、不同冰攻角、桩柱间不同位置时的冰力掩蔽系数。研究结果可供工程应用。

| Abstract: | There are few researches in the shield effect on ice force been reported in the world. In this paper, the shield effect on ice force among piles that in different positions of multi-pile structure is studied by ice force model tests. All the tests are performed in low temperature ice engineering laboratory. The mechanics and rules of shield effect are explored, and the ice force shield coefficients, corresponding to various ice thicknesses, pile diameters, ice attack angles and pile arrangements, are obtained. The study results can be applied in engineering. |
