| 摘 要： | 在对重力式码头进行检测评估时,需要对码头的安全性进行验算分析。文章结合某实际工程,通过建立有限元模型,结合规范中的相关公式,计算分析了码头整体的抗滑稳定性、抗倾稳定性及基床应力。研究表明,有限元法与传统规范计算方法相比,计算过程更简便,计算结果也更精确。 |
| 关 键 词： | 重力式码头 安全性评估 有限元法 抗滑稳定性 抗倾稳定性 基床应力 |

| Abstract: | When detecting and evaluating the gravity wharf,the safety of wharf should be calculated.Based on a practical engineering,the finite element model was established to calculate the stability against sliding,stability against tilting and the stress of foundation bed according to the formulas of standard method.The results show that the calculation process of the finite element method is more simple,and the results are more accurate compared with traditional standard method.It is demonstrated that the finite element method can be applied to the wharf safety evaluation successfully. |
| Keywords: | gravity wharf safety evaluation finite element method stability against sliding stability against tilting stress of foundation bed |
