摘　　要：文章结合山区复杂的地质条件、气候环境和日益增长的交通需求,针对KF山区高速公路改扩建中的路基与路面设计进行了系统分析,制订了切实可行的设计方案。具体而言,路基设计采用高压注浆、锚杆加固及多层防护措施,显著提升了路基的稳定性和抗滑能力;路面设计选用SMA-13改性沥青混凝土,并通过合理的结构层次和施工工艺,确保了路面的耐久性、抗滑性和平整度。结果表明,文章设计的改扩建方案不仅满足了高速公路的使用要求,还为类似山区公路的改扩建提供了有价值的参考依据。Based on the complex geological conditions,climatic environment and increasing traffic demand in mountainous areas,this paper makes a systematic analysis of the subgrade and pavement design in the expressway reconstruction and expansion in KF mountainous area,and formulates a feasible design scheme.Specifically,the subgrade design adopts high-pressure grouting,anchor-pile reinforcement and multi-layer protection measures,which significantly improves the stability and anti-sliding ability of the subgrade;the pavement design selects SMA-13 modified asphalt concrete,and ensures the durability,skid resistance and smoothness of the pavement through reasonable structural layers and construction techniques.The results show that the reconstruction and expansion scheme designed in this paper not only meets the use requirements of expressway,but also provides a valuable reference for the reconstruction and expansion of similar mountainous highways.
