摘　　要：软土路基处理是公路工程建设所涉及的一项重要内容,对公路工程的施工质量有着直接的影响,这也对软土路基处理技术提出了更高的要求。以天津西外环高速工程为背景,在简要分析该工程软土路基特点的基础上,对该工程软土路基处理技术及相应原理进行了阐述,并具体探讨了软土路基施工技术要点。经过比较选择了适合滨海软土地基处理的方法,并发展和提出了滨海软土地基处理的一系列新技术,经过实际应用得到满意的结果。Soft soil subgrade treatment is an important part of highway engineering construction, and has a direct impact on the construction quality of highway engineering. This also puts forward the higher requirements on soft soil subgrade treatment technology. Taking the Tianjin West Outer Ring Expressway Project as the background, this paper briefly analyzes the characteristics of the soft soil subgrade of this project, sets forth the treatment technology and corresponding principles of soft soil subgrade, and discusses the key points of soft soil subgrade construction technology in detail. After the comparison, the method suitable for treatment of coastal soft soil subgrade is selected, and a series of new technology for the treatment of coastal soft soil subgrade are developed and proposed. The satisfied results are achieved by the practical application.
