摘　　要：当海堤与高架桥梁交叉且工期接近时,交叉段的沉降对两者的安全性有很大影响。为此,拟建复合桩基模型,研究交叉段沉降对海堤、桥梁桥墩变位的影响,同时,为减小造价,给出建议复合桩基长度,可为沿海交通建设和围垦海堤的建设提供参考。The subsidence of cross section has a great influence on the construction security when the sea emban-kment is built across the viaduct and the construction period is close. Therefore, the com- posite pile foundation model is employed, and the effect of cross section subsidence on ,the deformation of sea embankment and bridge pier is analyzed. At the same time, in order to reduce the cost, we put for- ward suggestions of composite pile foundation length which can provide a reference for the coastal traffic and sea embankment construction.
