| Abstract: | The high pressure jet-grouting has been already proved to be an effective reinforcing technique for soft groud. It can meet the requirements that the train running can be uninterrupted, hence it has been widely used in soft ground improvement. According to the field survey document, the single pile bearing capacity, in this paper, is determined firstly, and then the foundation of pier and abutment design is obtained. After many years inspection the work indicate that it is very effective. |
