摘要
以省内某国道拓宽改造标段项目为研究案例,分析了影响路基拓宽改造的相关因素,并从新旧路基结合位置的不均匀沉降和开裂病害两个角度提出了针对性的施工质量控制措施,以切实提升省内既有高等级公路路基拓宽改造的施工控制质量和技术水平。
This paper analyses the relevant factors affecting the widening and transformation of subgrade,and from the uneven combination of new and old subgrade. From the perspectives of uniform settlement and crack diseases,specific construction quality control measures are put forward to effectively improve the quality and technical level of construction control for widening and renovation of existing high-grade highway roadbed in the province.
