Abstract: | Beijing-Shijiazhuang Passenger Dedicated Line (PDL) adopts ballastless track and the post-construction 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. |
