摘　　要：文章对国外某跨海大桥工程拟建区的工程地质条件进行了研究,认为全新世活动断裂对跨海大桥影响不大,拟建区内构造较稳定。拟建区内纵向上地基均匀性较差,而横向上各墩台内的地基均匀性较好,可能导致主桥和引桥之间的差异沉降问题,应加强该方面的治理措施研究。This paper studied the engineering geological conditions of the construction area of a foreign proposed sea bridge project.It was believed that the Holocene faults had little influence on the sea bridge,and the structure in the construction area was stable.In the construction area,the foundation was nonuniform in vertical,while the foundations of pier and abutments were uniform in horizon,which may lead to the differential settlement between the main bridge and the approach bridge,so the research on the treatment measures in this field should be strengthened.
