长春地区粉质粘土桩侧摩阻力研究方案

Study on the Side Frictional Resistance of Silty Clay in Changchun Area

长春市目前尚无总结区域的、参数的经验值,在进行桩基设计时计算单桩竖向极限承载力均是参照《建筑桩基技术规范》(JGJ94)中的桩的极限侧阻力标准值和桩的极限端阻力标准值表中数据取值计算.由于各地区地质条件的不同,参照规范给出的参数计算单桩竖向极限承载力无疑存在差异性,直接影响到桩基础工程的安全性和造价.本文通过研究,结合市场上最新的试验仪器,提出了长春地区粉质粘土层中桩侧摩阻力研究的方案,为有关科研单位或施工单位提供参考.

Changchun city, where is no area of a summary of the parameters, the experience value in pile foundation design calculation of single pile vertical ultimate bearing capacity are ＂technical code for building pile foundation＂ （ direction depending） in the pile of ultimate lateral resistance standard reference value and pile ultimate end resist- ance standard value table data value is calculated. Because of the difference of geological condition in each area, the calculation of the vertical ultimate bearing capacity of the single pile is different, which directly affects the safety and cost of pile foundation engineering. So through the research of this paper, combined with the market the latest test instrument is given. The research programme of study of pile shaft resistance in Changchun area silty clay, for the relevant scientific research units or construction units, we can reference the research program.
