文章通过对甘肃公路岩土区划的研究,探索性的提出了岩土区划的原则、方法和指标体系,并据此对甘肃省公路岩土区划进行了划分。为甘肃省公路工程建设中的规划、设计、施工、养护等趋利避害及材料使用等提供决策依据,对进一步开展公路自然区划研究具有一定的理论参考和借鉴意义。 Based on the research on the geotechnical division of Gansu highway, the article tentatively put forward the principle, method and index system of geotechnical division, and divided the division of highway geotechnical division in Gansu Province. It provides the decision-making basis for the planning, design, construction and maintenance of the highway construction in Gansu Province such as the advantages and disadvantages and the material usage, and has certain theoretical reference and reference significance for the further study on the natural division of the highway.
