Application of retaining structure with double-row piles in a hydraulic excavation

The retaining structure with double-row piles is used in an excavation of sluice. The internal force and displacement of the retaining structure with double-row piles are compared with those of MIDAS/GTS and double-row pile program of Lizheng. In the case of the same computational model, the calculated results are in good agreement. The sectional drawings of the retaining structure with double-row piles are analyzed from the internal force, displacement and different sharing ratios of lateral earth pressures on front-and rear-row piles. Finally, it provides certain reference value in designing the retaining structure with double-row piles. The displacement characteristics of double-row piles are preliminarily understood, by monitoring the displacement of the retaining structure with double-row piles.
