E江流域外交通公路深厚全风化层对公路工程的影响

Effect of Thick Completely Weathering Layer of Traffic Highway on Highway Engineering

E江流域水电开发对外交通公路路基及边坡岩性为花岗片麻岩,全风化层厚度大,且风化不均匀。通过对片麻岩风化机理、风化特征及工程区深厚全风化层工程特性、物理力学性质的分析,讨论了深厚全风化层对路基、桥梁、边坡及隧洞工程的影响,并对深厚全风化层地区勘察及施工提出地质建议。

Based on weathered mechanism of gneiss, weathered features, weathering characteristics of rocks of thick completely weathering layer and analysis of physical and mechanical properties, the paper discusses the effect of thick completely weathering layer on roadbed, bridges, slope amd tennel and proposes recommendations of survey and construction.
