| Abstract: | Basic on further analysis on the characteristics of the Pilot-tunnel & Pile(Column) top-down method,key design technology points were discussed on the bearing capacity,deformation and stability of the main forced components which include the side piles,the middle concrete filled steel tubular piles,the middle pile foundation,the bar foundation,etc..Some measures for improving the soil stability during the construction and the bearing capacity of soil foundation are presented.Moreover,the principle of the rational buried depth for metro station built by the Pilot-tunnel & Pile(Column) top-down method is suggested. |
