为了保证公路路基强度满足施工要求,需要对不合格地基进行换填施工,分析了路基换填的注意事项,提出通过设置集水井、实验路段、开挖沟槽、填换、摊铺、碾压等措施提高公路地基强度,希望能为类似工程提供参考.%In order to ensure the strength of highway subgrade to meet the construction requirements, it is necessary to replace the unqualified foundation. This paper analyzes the matters needing attention in subgrade filling, and puts forward some measures to improve the strength of highway subgrade, such as setting up catchment wells, obtaining technical parameters from experimental sections, excavating trenches, filling and replacing, paving and rolling. I hope this analysis can provide a reference for you.
