压密注浆对土体微观结构的影响研究

依托唐津高速公路（K61＋068～K94＋000）段维修工程的具体实践,对路基注浆前后土体微观结构类型、微观结构参数的变化进行研究,揭示了注浆前后土体性质发生变化的内在机理,从微观角度研究压密注浆法对提高病害路基强度的效果。通过研究证明了压密注浆是进行路基加固的有效手段。

Study of Influence of Injection Grout on Microcosmic Structure of Soil

Based on the practice of maintenance works in Tangshan-Tianjin Expressway(K61+068~K94+000),the article studies the variations of the microcosmic structure types and parameters of the soil before and after the roadbed grouting,and makes public the internal mechanism of variations for soil character before and after grouting,and studies the effect of the grouting method to enhance the strength of the fault roadbed from the microcosmic angle.The study proves the injection grout is the efficient means for the r...
