摘　　要：以华东某岛室内船坞底板PHC管桩桩基的静力压桩施工为例,对静力压桩在粉质黏土夹砂层中所出现的问题予以分析研究,并初步提出了解决的办法,为今后类似土层沉桩工艺的选择提供了借鉴。Taking the static pressure pile construction of PHC pipe pile foundation at the bottom plate of an indoor dock in East China as an example,the problems that occur in the static pressure pile in the silty clay sand inclusion layer are analyzed and studied,and a preliminary solution is proposed,which provides reference for the selection of similar soil layer pile sinking technology in the future.

关 键 词：静力 夹砂 比贯入阻力 沉桩
