    Abstract
  • Taking a double-piles foundation pit in Shenzhen as an example, the monitoring deformation of pit retaining structures as well as adjacent buildings were analyzed. The former 1/3 period of excavation stage was the most fast increase period of lateral deformation of double-piles retaining structure, and the significant increase in settlement of adjacent buildings occured in the latter 2/3 period. The monitoring data shows that the lateral deformation form of double-piles structure is changeable with some factors. The cement soil curtain between piles effectively increases the lateral stiffness of double-piles retaining structure.
