    • Abstract
  • Scattered row pile-soil-nailing wall retaining structure is a new support form which combineds soil-nailing wall and sparse row piles. It’s one of important directions of the composite soil-nailing wall. This new retaining structure is used in engineering practices, but a unified method is not available for analysis of its overall stability. The suitability of LIU Bin's method and the strength reduction method in calculating the overall stability safety factor is discussed based on the centrifugal model tests. The results indicate that LIU Bin's method is more suitable for the overall stability analysis of scattered pile-soil-nailing composite retaining system for foundation pits.
