采用柱状锤强夯法解决重力式码头背后回填地基沉降问题

摘要

Due to the lack of treating technology process for the backfill foundation in the rear of gravity wharf, large post-construction settlement of the region occurs,which may influence the appearance quality,even the functions of the wharf. Based on Jinzhou Port No.2 Basin Container Terminal Phase-2 project,the construction technologies and effect of pillar-hammer tamping method is indicated,which will be used to treat the backfill foundation in the rear of gravity wharf. The research results will provide references for similar project.%重力式码头背后回填地基暂无较好的处理工艺，导致该区域后期沉降普遍较大，影响码头观感质量，严重时影响码头使用功能。本文结合锦州港第二港池集装箱码头二期工程，介绍采用柱状锤强夯法处理重力式码头背后回填地基的施工工艺及效果，希望能为类似工程的施工提供借鉴经验。
