软弱地基处理CFG桩体材料研究

Research on CFG Pile Body Material for Treating Soft Ground

为实现节能减排、缓解资源短缺的目标、降低工程造价,在国内某新建高速铁路A市东站软弱地基CFG桩施工中通过对桩体混凝土中的河砂及粉煤灰等材料进行研究,成功地采用尾砂替代河砂、原灰替代粉煤灰等优化节能方案,在不改变CFG桩体设计强度、保证施工质量的前提下,达到了软基处理的效果。

In order to realize energy saving emission reducing,release resource shortage and reduce project cost,the CFG pile construction for the soft ground of a new-built high speed railroad in home successfully adopted the optimization energy saving scheme including tailings instead of river sand original fly ash instead of fly ash,by researching material in pile body concrete,like river sand fly ash.It achieved the soft ground treatment effect,under the premise that design strength of CFG pile body was not changed and construction quality was guaranteed.
