Abstract

Abstract: The influence of red-layer soft rock to the high grade highway construction is great. This paper expatiates the distributes of red-layer soft rock in western region in China and its geology characteristic, describes the rock construction characteristic and engineering characteristic of the red-layer soft rock, including the transform characteristic, the anti-shear strength characteristic, water reasonableness speciality and soft rock mezzanine problem, on the basis of this, further analyzing the

Key words: red-layer soft rock, construction characteristic, engineering characteristic, roadbase construction, stability

摘要： 红层软岩对于高等级公路建设影响较大。本文阐述了我国西部红层软岩的分布及其地质特性，描述了红层软岩的岩体结构特征和工程特性，包括变形特征、抗剪强度特征、水理性质和软岩夹层问题，在此基础上，进一步分析了红层软岩对公路路基结构形式和稳定性的影响，并提出了相关的处治措施。
