The Research Of "soil Nails And Pile-anchor" Joint Support In Yantai Binhai Square Construction Technology

Recent year, along with urban construction's development, three dimensional city space has been requested to developed day by day, the deep foundation ditch project also increases along with it, which lead to both the project scale and the technology getting more and more difficult. Firstly this paper comprehensively formulates the pattern and the development state of the deep foundation ditch,then take the Yantai Binhai square's deep foundation ditch project as an example, analyzes this project's shoring of trench program alternatives.Under deep foundation ditch in soft ground circumstances,soil nailing walls and piles supporting the anchor type has been proposed.Through design, construction and monitor and so on, the program has been implementated and the feasibility of this program has been further confirmed.Under deep foundation ditch in soft ground circumstances,this programme can guarantee the quality of construction,the construction period,the security and other aspects of the request, and can greatly reduce the costs of the project,and provide a reference and suggestion for the design and construction.
