| 摘 要： | 通过在预应力高强混凝土管桩（PHC桩）的桩顶、桩端及各节桩接桩分界面粘贴应变片的精细静荷载试验,研究了沈阳地区高强预应力混凝土管桩的荷载传递机理,分析了侧阻力、端阻力的变化规律,实测了压桩力与入土深度的相互关系.考虑到沈阳地区土质特性,PHC管桩在本地区呈摩擦端承型,而不是南方地区的摩擦型桩.

| Abstract: | Based on the loading test on PHC piles with strain gauges at the top and tip the piles and at the interface of each pile section,the load transfer mechanism of PHC pile in Shenyang district is studied in this paper.The behaviors of shaft resistance and tip resistance are then analyzed.The relations of jacking pressure to the embedded depth are measured thereafter.Taking into account the soil characters of Shenyang district,the jacked PHC pile is friction and end-bearing pile instead of pure friction pile in... |
