摘要 文章针对特殊土质的峡谷地段公路施工难题,以广西靖西县某公路边坡支护工程为例,对常规的施工方法进行了一系列的改进,提出了实施超高脚手架与悬挑型钢协同承载、下部排桩柱锚杆网喷混凝土复合施工、上部锚杆网喷混凝土应力分散等创新组合的峡谷边坡关键施工技术,为峡谷段公路膨胀土边坡施工提供参考经验。 For the construction difficulty of special soil at canyon highway section, with the slope supporting engineering of a highway in Jingxi County as the example,the article conducted a series of improvements to the conventional construction method, proposed the canyon slope key construction technology with innovative combination of implementing the collaborative load bearing of ultra-high scaffolding with cantilevered steel, the composite construction of lower row piles anchor net spraying concrete, and the stress dispersion of upper anchor net spraying concrete, providing the reference and experience for the expansive soil slope construction at canyon highway section.
