Abstract: Based on a large number of measured data for a deep excavation in-situ, the corresponding bending moments, deformation characteristics and the earth pressure distribution of a double-row piles retaining structure are studied. Some problems are analyzed, including the space effect of deep excavation, the effect of cap beam on earth pressure, the relationship between retaining structure deformation and the earth pressure distribution, and the mechanism of action between retaining structure and soil. The studies show that the earth pressure distributions on the double-row piles retaining structure are quite complicated, and are different from those obtained by the classical Rankine’s or Coulomb’s earth pressure theory, which supply a basis for the design model of double-row piles retaining structure.

Key words: deep foundation pit, deformation；retaining structure, earth pressure
