石灰改良膨胀土力学性质的研究
摘要:膨胀+主要是由强亲水性粘土矿物蒙脱石和伊利石组成的,是具有膨胀性、多裂隙性和超固结性的高塑性粘性土。在铁路施工中,膨胀土不能直接作为路基填土,必需进行改良。通过室内试验的方法来讨论石灰改良膨胀土的力学性质在各种影响因素下的变化规律。
Abstract:Expansive soil consists of montmorillonite and illite,which are all clay minerals with strong hydrophilicity,so it is a kind of clay with high plasticity,and has characteristics of high swelling or shrinking deformation,crack and over consolidation In the construction of the railway, expansive soil can not be used as the road bed directly, without being improved. The change regularity of the mechanical character of lime improved expansive soil under the influence of the various factors is discussed
