摘　　要：路基施工质量检测技术落后和检测密度过低是导致路 基工后沉降过大及产生路基病害的主导因素,在指出目前检测 技术不足的基础上,提出解决检测技术落后和检测密度低的技 术途径,论述了面波测试技术用于路基施工质量检测的技术原 理,并进行了相应的可行性分析。Outdated detection technology and low detection density are main causes for large settlement and subgrade defects. Technical measures were raised against these causes, and principles for surface wave detection were given, and feasibility analysis was made of its application to subgrade detection.

关 键 词：铁路路基 工后沉降量 地基系数 检测指标 检测密度 面波波速
