Abstract: It is the key problem for the combined retaining structure to distribute the active earth pressure to the anchored-pile and the soil nailing reasonably.Based on the lateral deformation curve and data of the combined retaining structure of anchored-pile and the soil nailing,the method could be established and used to calculate the distribution of the active earth pressure in the combined structure.With the application of this method in deep foundation pit,the engineer could practise the efficiency of the anc...
