| 摘 要： | 为降低大面积冰排对滩海区海上结构物的作用力,设计了一种新型破冰结构.利用破冰结构使大面积冰排发生弯曲破坏变成面积较小的破碎冰块,降低破冰结构后方被保护结构物上的冰力.以圆柱桩为例,通过试验对比冰排对圆柱桩挤压力以及破碎后的冰块对圆柱桩撞击力,检验破冰结构对圆柱桩的保护能力.另外,为检验破冰结构的稳定性,测试了冰排对破冰...

| Abstract: | A new icebreaking structure was designed to decrease large forces of ice floes on offshore structures in shallow waters.The structure was used to break the large-area ice floes into small pieces to reduce the ice forces on the protected maritime structures at the back by breaking the floating ice in bending.A column pile was taken as an example to inspect the protection effect of the new icebreaking structure.A series of physical model tests were conducted to simulate the crushing loads of ice floes and the... |
