摘　　要：京石客运专线采用无砟轨道,工后沉降控制是客运专线路基施工的关键技术。根据工程地质条件和工程实际,采用强夯法对京石客运专线个别段落路基工程进行处理,设备简单,施工方便,经济易行。通过地基土试验检测和沉降观测,评估结果证实,强夯法处理该地基效果良好。Beijing-Shijiazhuang Passenger Dedicated Line （PDL） adopts ballastless track and the postconstruction settlement of the subgrade is the key thereof. Based on the engineering geological conditions and the practice therein, dynamic compaction is used in certain sections of Beijing-Shijiazhuang PDL. Dynamic compaction as a means to reinforce the foundation is economical and convenient with the equipments very simple. Through foundation soil tests and settlement observation and assessment, it is proved to be a good method for such foundation treatment.
