钻孔灌注桩用于公路软土地基施工研究

摘要

软土地基是公路施工常见通病，因软土层结构具有明显的脆弱性，对公路结构性能产生诸多功能性危害。新时期公路施工技术实现了优化转变，采用钻孔灌注桩处理软土地基问题取得良好效果，为公路现代化建设提供技术支撑。结合软土地基特点及其危害性，分析了软土路段公路主要病害形式，提出钻孔灌注桩用于软土地基处理的工艺方案。%Soft soil foundation in highway construction is the common disease, because of the soft soil layer structure has obvious vulnerability, many functional damage of highway structure performance. Optimization of highway construction technology to achieve the transformation in the new period, dealing with soft soil foundation using bored piles obtain good effect, provide technical support for the modernization of highway construction. Combining with the characteristics of soft soil foundation and its harmfulness, analyzes the main forms of these diseases, and soft soil road highway bored piles is put forward for the processing plan of soft soil foundation treatment.
