摘　　要：在连云港某围埝的建设过程中,采用水下真空预压技术对围埝下的软土地基进行加固。在保证地基稳定的基础上缩小了围埝的断面尺寸,既节省了大量建筑材料,又缩短了施工工期,取得了满意的效果。该方法可在海上围埝工程建设中推广应用。Underwater vacuum preloading technique was applied to improve the offshore soft soil cofferdam foundation in Lianyungang. The cross-section was properly reduced on the premise that the foundation was kept stable. This method has not only saved many construction materials, but also shortened the construction period, resulting in a satisfactory result. It is nec- essary to further recommend this method in engineering practice.
