摘要
广元到巴中高速公路沿线分布有广泛的红层堆积体高边坡。红层堆积体是红层地区一种特殊的坡体结构类别,不同堆积物形成的堆积体,特别是堆积体内含大量块石夹土或孤石的情况下,结构不均匀性非常明显,堆积体自身结构松散。块石土堆积体为主要的分布最广泛的堆积类型,但沿线三种不同类型的堆积地区均有其代表性堆积体结构:古滑坡地区以粘土层下卧块石土堆积体为主;岩堆地区主要为层状堆积体;而一般性堆积体地区广泛分布有块石土粘土夹杂大孤石堆积体。对红层堆积体坡体结构在不同堆积地区的详细分类,为进一步研究红层堆积体高边坡的破坏机理和致灾模式提供了初步依据。
There are widely distributing high red bed accumulation body slopes along the Guangyuan-Bazhong Expressway.The red bed accumulation body is a special structure category in red bed area.There are different accumulations,especially those containing large amount of mass rock and solitary stone,their inhomogeneity is very obvious,and its their own structure is unconsolidated.Mass rock and soil accumulation body is the most broad distributed type.Along the expressway,there are three different pattern areas and each of them has their representative accumulation structure.Mass rock and soil beneath clay layer accumulation body is the main type in ancient landslide area.Layered accumulation body is the main type in rock heap area.And mass rock and clay mixed up with big solitary stone accumulation body is widely distributed in generality accumulation area.The detailed classifications results of red bed accumulation body provide primary bases for analyzing the disease patterns and failure mechanism in diverse red bed accumulation body areas.
