摘　　要：依托某防波堤项目,针对工程区域波浪大、地质条件差、工期紧等复杂条件下防波堤结构设计选型问题,采用理论分析及数值计算方法,从结构受力特点、耐久性使用、施工难易程度、施工工期及工程造价等多方面对地基处理和结构进行对比,最终推荐较短时间内可对港区形成有效掩护的沉箱直立堤结构方案(地基处理采用水泥搅拌桩)。研究成果可为类似工程的结构选型提供参考。Based on a breakwater project,aiming at the problems of breakwater structure design selection under complex conditions such as large waves in the engineering area,poor geological conditions and tight construction period,this paper compares and discusses the foundation treatment and structures from the aspects of structural stress characteristics,durability,construction difficulty,construction period and project cost using theoretical analysis and numerical calculation.Finally,the vertical caisson embankment structure scheme(with ground treatment using cement mixed piles)which can provide effective protection to the harbor area within a relatively short period is recommended.The research results can provide reference for the structure selection of similar projects.
