摘要
结合北方某重力式深水 ( -1 6.0 m)码头沉箱后壁 1 4.5 m范围的回填风化砂经深层振密处理这一工程实例 ,介绍了回填砂振密的技术要求、施工工艺和方法及振密效果的检测。同时对施工与检测中的某些技术问题提出了自己的看法。
Taking the deep vibro densification consolidation work of a 16 m weathered sand backfilled subgrade bebind the backwall of caisson of a gravity type deep water wharf as an example, some problems with the deep vibro densification consolidation with backfilled weathered sand, including technical requirements, construction technology and method and test of vibro densification effect are introduced, and the authors also give their own opinions on some technical probleme in the construction and test.
