摘要
加芯水泥土搅拌桩是一种用于处理软土地基的新型桩,目前该种桩型在国内外的研究尚未完善.本文通过试验分析了加芯水泥土搅拌桩在竖向荷载作用下的荷载传递机理以及单桩破坏模式,根据破坏模式及影响因素推导出单桩承载力的计算公式.并讨论了该桩型的优化设计,提出了最优含芯率和最优芯长比等结构因素.
A new kind of pile named concrete - cored DCM pile is developed for medium load design in soft clay ground. The load capacity of this new pile is analyzed in this paper. Based on several experiments, this paper analyses load transfer mechanics and failure mode. Discusses the formula of load capacity and the pile optimism design, including the selection of radium and the length.
