摘要
结合北方某港已建深水码头沉箱后30m范围内回填风化砂地基的深层加固工程,介绍砂基振密的设计与施工方法、质量控制及加固效果的检测等。文中还对施工与检测中的相关问题提出了一些见解。
This paper,combined with the deep strengthening of weathered sand fill foundation within the range of 30 m behind the caissons for the completed deep water berth at a port in the north of China,introduces the design and construction method of compacting and vibrating sand fill foundation,and quality control and improvement effect,etc.Several opinions of relative issues induced from the construction projects and inspection are proposed.
