摘　　要：某大型陆域形成地基处理工程的实施需要配合水上施工作业,但存在部分区域的水深条件不满足施工船舶的吃水要求的矛盾;另外,工程实施还面临疏浚土方外抛受限的困难。施工图设计阶段结合工程地质特点和施工条件进行了方案的优化分区设计,结合原泥面标高、软土层整体厚度及工后沉降要求,合理设置吹填区位置,细化了陆域形成的分区。本工程方案的优化用以指导本标段场地造陆及地基处理施工,也为本地区其他造陆工程项目提供一定的借鉴意义。The execution of a large land formation and foundation treatment works requires the assistance in waterborne operation,but the water depth conditions in some areas do not meet the draft requirements of construction ships.In addition,the disposal of dredged earthworks is also a problem to solve during construction.In the stage of detailed design,an optimized zoning design was carried out based on the combination of engineering geological characteristics and local conditions.The comprehensive study of original mud surface elevation,overall thickness of soft soil layer,and post-construction settlement requirements led to reasonable layout of dredger-filled area as well as refined land formation zones.The optimum plan applies to the land reclamation and foundation treatment within the range of this bid section,and also provides a certain reference for other local land reclamation works.
