以秦山核电公司排水隧道工程为背景，研究穿堤隧道盾构施工引起的海堤堤顶沉降问题。通过 Peck 经验公式和 PLAXIS 有限元分别对盾构施工引起的堤顶沉降进行计算，两种方法计算结果较吻合。计算结果表明：堤顶横向沉降呈对称分布，隧道轴线正上方地表沉降最大，最大沉降量在10 mm 左右，向左右两侧沉降逐渐减小；在堤顶相同位置，沉降量随着土体损失量的增大而增大。同时提出了堤顶沉降的控制措施，以减小沉降，为盾构隧道的顺利实施提供了依据。

On the basis of the drainage tunnel project of Qinshan Nuclear Power Company,in order to research the ground settlement of levee induced by shield tunneling,the ground settlement was predicted by Peck′s empirical formula and PLAXIS finite element method,and both the methods got the uniform results.The results show that the ground settle-ment is symmetrical,the ground settlement above tunnel axis is largest,the maximum settlement is about 10 mm,and the settlements to left and right side decrease gradually.At the same position,the ground settlement will increase with the increasing of ground loss.The control measures of the settlement are proposed to reduce the settlement,which could pro-vide some references for the smooth implementation of tunnel projects.
