| Abstract: | Double-row piles retaining structure system was a newly shoring system in deep excavation engineering.It possessed the advantages of excellent force performance,huge lateral rigidity,and non-bracing supporting system etc.So it would be able to get extensive use in deeper,bigger foundation pit,especially in soft soil area.Based on the deep foundation pit of Wuhan TIMES Plaza,and aimed at application of the Double-row Piles retaining system in Wuhan Area(I terrace of the Yangtze River),the behavior and stabil... |
