摘　　要：文章以浙东沿海某电力基础工程项目为背景,针对浙东沿海吹填场地基桩负摩阻力进行现场试验,分析基桩在原位条件下的负摩阻力、桩身下拉荷载及桩土相对位移随时间发展变化的规律,并探讨次固结影响下浙东沿海吹填场地桩基负摩阻力发展趋势。该研究成果可为浙东沿海地区快速成陆的吹填场地基桩工程的设计和施工提供参考。Taking an electric power foundation project along the coast of eastern Zhejiang as the project background, this paper carries out field tests on the negative friction of foundation pile in the coastal blow-fill site of eastern Zhejiang, analyzes the development and change law of negative friction of foundation pile, tensile load of pile body and relative displacement of pile and soil with time under the in-situ condition, and discusses the development trend of negative friction of pile foundation in the coastal blow-fill site of eastern Zhejiang under the influence of secondary consolidation. The research results can provide reference for the design and construction of foundation pile in the rapid land-forming blow-fill site in the coastal area of eastern Zhejiang.
