Retaining structures combined pile-anchor with soil nails considering vertical soil arch;

On the characteristics of the pile-anchor supporting structure of the door frame type reinforced concrete

In this article,authors introduce the design and construction of composite supporting technique of soil nailing and pile-anchor in a deep foundation pit support under complex environment and geological conditions,and mainly present the design measures and technical measures under special condition.

In combination with practical example of a foundation pit supporting in Changsha,technical and economic comparisons and analyses were made for several support schemes,the optimal method is combined support of soil nailing wall and pile anchor,and the design method and construction technique of the combined support technology were introduced in this paper.

In view of complex peripheral environment in the site of foundation pit of Science and Teaching Building of Wu- han First Hospital,information construction and combined supporting method were adopted with pile anchor retaining,soil nailing wall with mesh shot-concrete and concrete anchor.
