摘　　要：交通的进步和城市地区的快速发展凸显了道路基础设施对当代社会进步的重要性,然而,土路基在长期使用过程中常常面临变形和破坏的问题,给道路的使用和维护带来了很大的挑战,研究泡沫轻质土路基的变形特性和修筑技术具有相当重要的理论和实践意义。文章通过对泡沫轻质土路基的研究,探索其变形特性及修筑技术。研究结果表明,在施工过程中,每层泡沫轻质土路基沉降量在2cm以下,路面施工完成后的沉降量大约为5.3cm;路基中心线10m范围内基底应力分布变化形式几乎一致,路基边坡范围的应力产生了较大的变化。The progress of transport and the rapid development of urban areas highlight the importance of road infrastructure to the progress of contemporary society,however,earth roadbeds are often faced with deformation and damage during long-term use,bringing great challenges to the use and maintenance of roads,so the study of the deformation characteristics of the foam lightweight earth roadbeds and the construction technology is of considerable theoretical and practical significance.The article explores the deformation characteristics and construction technology of foam lightweight soil roadbed through the study of foam lightweight soil roadbed,and the results show that during the construction process,the settlement of each layer of foam lightweight soil roadbed is below 2cm,and the settlement after the completion of pavement construction is about 5.3cm;the form of change of the distribution of the substrate stress within the range of 10m of the centre line of the roadbed is almost the same,and the stress in the range of the roadbed side slope produces a large change.
