摘　　要：随着国家基础设施建设的不断推进,公路工程在发展过程中面临了众多技术难题,特别是在膨胀土地区进行路基填筑时,稳定性风险变得尤为突出。由于膨胀土的胀缩特性,常引发路基沉降、开裂等问题,严重威胁着公路的使用寿命及安全。对此,文中针对这一技术难题,深入探讨了膨胀土路基填筑的施工技术,详细分析了膨胀土的特性及其对路基稳定性的影响,并研究了处理工艺、施工重点及质量控制措施。通过提出的针对性施工方案,为在膨胀土地区开展公路工程建设提供了科学依据及技术支持,这些研究成果不仅对提升膨胀土地区公路工程的施工技术具有指导意义,也为相关领域的进一步研究奠定了基础。With the continuous promotion of national infrastructure construction,highway engineering faces numerous technical challenges in the development process,especially when filling roadbeds in expansive soil areas,stability risks become particularly prominent.Due to the expansion and contraction characteristics of expansive soil,it often causes problems such as roadbed settlement and cracking,seriously threatening the service life and safety of highways.In response to this technical challenge,the article delves into the construction technology of expansive soil subgrade filling,analyzes in detail the characteristics of expansive soil and its impact on subgrade stability,and studies the treatment process,construction focus,and quality control measures.The proposed targeted construction plan provides scientific basis and technical support for highway engineering construction in expansive soil areas.These research results not only have guiding significance for improving the construction technology of highway engineering in expansive soil areas,but also lay a foundation for further research in related fields.
