特殊条件下公路边坡病害变形类型和特征

随着我国高速公路建设的飞速发展,许多在建、拟建高速公路正在向山区延伸,使得高速公路建设不可避免地遇到众多的边坡失稳破坏和滑坡问题,特别是当路线通过特殊地质地段时,产生的边坡病害集中、类型复杂、规模大、治理难度较大。本文对坡体病害地段、特殊岩土地段、高山峡谷地段和顺层地段的高边坡病害变形类型和特征进行初步总结和探讨。

Characteristics and Deformation Types of Slope Disasters along Road under Special Conditions

With rapidly development of expressway construction,many roads that are being constructed or planning to be constructed are going through mountainous areas.It is inevitably to encounter many unstable slope and landslide problems during the construction,especially when the road goes through special geological section,many large-scale and complex slope disasters occur in this section and it's hard to control.Consequently,the paper sums up and discusses characteristics and deformation types of high slope disasters in slope disaster section,special geotechnical section,mountainous valley section and bedding section.
