山区公路水毁机理与抗毁结构分析 --以凉山地区为例

以凉山地区境内的公路水毁为例，对山区公路水毁发育机理进行了分析研究，并针对本地区的地形、地貌、地质构造以及气象水文条件提出了有效的路基抗毁结构.研究表明，按不良地质现象及力学机制可将该区的公路水毁分为4类：重力剪切破坏型、泥石流诱发型、河流破坏型和地基失效.这一成因研究丰富了公路水毁学的科学内涵.，Base-watering of highways is the main wasting of highway in mountainous area. This paper analyzes base-watering of highways in mountainous area, taking base-watering of highways in Liangshan area as an example. And we suggest the effective anti-destroy structure against topography, geomorphology, tectonic and hydro-meteorology of this area. The base-watering of highways of this area can be divided into four types, i. e. slide inducing, mud-rock flow inducing, river flow inducing, and foundation losing efficacy. This classification has enriched connotation of base-watering of highways.，
