| 摘 要： | 斜坡堤抗冰结构明显优于垂直结构，它使冰排破坏形式以弯曲破坏为主，大大降低作用在结构上的冰荷载．出于抵抗波浪和冰排的作用，在斜坡表面排放“扭王字块块体”预制件，为维修更换提供了极大方便．试验考察了扭王字块块体在冰排作用下的稳定性和作用于斜坡上的冰荷载．试验结果表明：斜坡角度的设计对降低水平作用的冰荷载直接而有效；扭王字块块体的护坡工艺是实用和可靠的．

| Abstract: | Anti-ice slope embankment structure is significantly superior to the vertical structure, which will form ice rafting damage to the bending failure and greatly reduce the ice load on the structure. For resistance of waves and ice rafting, Wang word-twisting prefabricated parts were put on the slope surface, which is convenient for maintenance and replacement. The stability of Wang word-twisting blocks in the ice rafting and the ice load on the slope were investigated. Experiment results indicate that the design of the slope angle helps reduce the horizontal ice load directly and effectively, while Wang word-twisting blocks are practical and reliable in the ice rafting. |
