【摘要】 描述了安徽膨胀土层的胀缩特性及其它物理力学性质，说明这种土层具有胀缩、裂隙及超固结的特性。结合本地区于六七十年代开挖而相隔数十年以后发生的几个典型滑坡，从土层埋藏条件、工程地质条件及滑坡治理的实践，分析了膨胀土开挖边坡的滑坡成因、滑动面形态特征及滑坡治理效果。并就膨胀土地区的开挖边坡中与稳定性有关的几个问题：抗剪强度和强度衰减软化、开挖边坡设计及滑坡治理方法的选择等进行了探讨。更多还原

【Abstract】 The physical properties and engineering behaviour of Anhui expansive soil are described, this kind of soil takes the characteristic of swelling-shrinkage, fissility and overconsolidation. Combined with several typical landslides, the landslide-forming factors, the properties of landslide shape and the effect of landslide treatment are analysed from the point of the buried strata,The engineering geological condition and landslide treatment. Several problems related to landslide stability including the shear strength and its attenuation, the design of cut slope and the determination of landslide treatment method are discussed in this paper.更多还原
