软土路堤水泥土搅拌桩设计及整体稳定性分析

Analysis on soft embankment cement-soil mixing pile design and integral stability

结合珠三角地区河相沉积软土特性,选取水泥土搅拌桩作为软基处理方案,通过现场试桩后确定设计、施工等参数,并根据沿线现场地形地貌特征,提出了铁路设计中和运营后应注意的要点,为今后珠三角地区的软土地基处理提供参考借鉴。

Combining with river soft clay properties in Pearl River Delta Area,the paper selects cement-soil mixing pile as soft foundation treatment scheme,determines design and construction and other parameters through in-situ pile testing,and puts forward railway design and operation points according to morphological features,which has provided some guidance for soft foundation treatment in Pearl River Delta Area.
