  vacuum well-point dewatering
     Based on the analysis of stress path characteristics,influence depth of reinforcement and mechanism of consolidation deformation,this paper reveals the characteristics of stress and deformation in the bridge-slope subgrade reinforced by vacuum well-point dewatering combined with equal preload. By comparison of the settlements determined by conventional grouting method and by proposed method,it is proved that the proposed method is reasonable and economical.
     通过对真空井点降水联合等载预压这种加固新方法在加固过程中土体应力路径特征、加固影响深度及加固后的土体固结变形机理的分析,揭示了在该加固方法条件下地基土中应力变化及其相应的变形规律,并与注浆加固进行土体物理力学指标和工后沉降对比,从而闸明了该方法在桥坡路基加固中较传统注浆加固方法更具有合理性与经济性。
