| 摘 要： | 强夯法处理湿陷性黄土地基以其经济、施工速度快且适用性广而被工程界广泛应用,其加固效果不仅与强夯的施工参数有关,还与被加固地基的工程地质条件密切相关。本文通过某工程施工前在现场选取两个典型试验区进行8000kN.m超高能级强夯下加固效果的对比试验,探讨了湿陷性黄土的含水量对强夯效果的影响,同时也探讨了由于地层层序等工程地质条件差异对强夯主加固深度产生的影响,为下一步指导大面积的强夯施工和加固同类地基的设计提供重要依据。

| Abstract: | Because of its economy, rapid construction and wide applicability, tamping which is used to treat collapsible loess has been applied widely in engineering field, its reinforcement effect has great relation with not only construction parameters, but also engineering geology conditions. Through the reinforcement effect comparing tests with 8000kN·m super-energy power tamping in typical tests area before project construction, the paper discusses the influence of water content of collapsible loess on reinforcement effect, at the same time, the influence of geology condition difference of stratigraphic sequence on reinforcement depth is discussed, which supplies important guide basis for extensive tamping construction and similar foundation reinforcement design. |
