无砂砼小桩处理黄土路基的增湿变形计算

阐述了用无砂砼小桩处理湿陷性黄土路基时，由高填方路基预加荷载提供黄土湿陷起始应力，注浆过程中使桩孔周围的部分黄土提前发生湿陷变形，从而改善黄土结构的湿陷性，保证土体结构的水稳性．并推导出无砂砼小桩处理黄土路基的增湿变形计算公式，为黄土地区采用无砂砼小桩后处理高填方路基提供变形计算依据．

The Prewet Deformation Calculation of Disposing Loess Roadbed with Small Non-Sand Concrete Pile

This paper analyzed when disposing the collapsible loess roadbed with small non-sand concrete pile, surcharging handled by the high fill subgrade to provide pre-loading contained initial collapsible stress,grouting process will move around the pile hole early part of the loess occurred collapsible deformation,so that the colla-psible of the loess structure have significantly improved and the water stable of the soil structure be guaranteed. And educe the prewet deformation calculation expressions of disposi...
