| Abstract: | Combined with geological exploration report analysis to the engineering geology condition of photoelectric r&d base,authors clear the characteristics and difficulties of project.Through comparing with a variety of foundation excavation supporting schemes,authors make a reasonable choice of construction scheme that filling weathered sand to the soft soil slope and combining ballast aggregate changing with anchor,soil nailing support system for excavation slope processing,and the scheme is analyzed theoretically and designed,finally,the concrete construction technology is got.After monitoring by work,the construction technology for the treatment of soft soil foundation excavation slope has obtained good effect. |
