| 摘 要： | 说明了在冰排与斜面结构相互作用分析中应当考虑水平力的附加弯矩作用，按照纵横弯曲模式进行了冰荷载和冰的断裂长度分析，给出了简化的公式和算例。结果表明，上述考虑将使冰力和冰的断裂长度趋于减小。预测的断裂长度与现场观测结果大致吻合。

| Abstract: | According to the simultaneous longitudinal and transverse loading mode, the formulae of ice load and broken length in brittle failure are established for analyzing the interaction between ice ocover and slope structure.Calculation examples are given. It is shown that the ice load tends to lower and the broken length become shorter in this mode. The broken length predicted by the formula is roughly in accordance with the observed data in site. |

| Keywords: | simultaneously longitudinal and transverse loading mode ice load broken length slope structure |
