| 摘 要： | 海堤工程地基沉降修正系数的正确选取，关系到利用分层总和法计算地基沉降量的精度．依据某围垦工程原位监测数据，利用曲线拟合法的指数曲线配合法，对莱围垦工程海堤外海侧镇压平台及堤轴线附近的沉降观测点数据进行了分析计算，得到了主堤下地基的主固结沉降量及最终沉降量，并推算了沉降修正系数；同时利用分层总和法，计算了地基的主固结沉降量，验证了本方法的合理性． |
| 关 键 词： | 海堤地基 指数曲线 沉降修正系数 |

| Abstract: | The correct selection of settlement correction factor in seawall foundation plays an important role in the calculating accuracy of the foundation settlement by layerwise summation method. Based on the exponential curve model and the measured data from the reclamarion observation, the ultimate settlement of the main dam is calculated and a reasonable, workable solution is provided. A case study shows the calculating method of settlement correction factor is a realistic one. |
| Keywords: | seawall foundation e-pcurve layetwise summation method exponential curve correction factor of settlement |
