Abstract

An excavation of 10.5m deep and 110m x 70m in plane with double-row pile retaining structure in soft clay has been completed, which is of severa1 advantages, such as elimination of lateral deflection and ground surface settlement, low cost and short duration of excavation. This paper presents tile design considerations, procedure of construction and excavation, behavior of this type of retaining structure. The FEM analysis has been carried for prediction of lateral deflection and stress, the results from FEM method conformed well with field measurement, some conclusions drawn from the design and construction Mil be valuable for future construction in similar engineering.

Behavior of Double-row Pile Retaining Structure for Deep Excavation in Soft Clay

St. Louis, Missouri

An excavation of 10.5m deep and 110m x 70m in plane with double-row pile retaining structure in soft clay has been completed, which is of severa1 advantages, such as elimination of lateral deflection and ground surface settlement, low cost and short duration of excavation. This paper presents tile design considerations, procedure of construction and excavation, behavior of this type of retaining structure. The FEM analysis has been carried for prediction of lateral deflection and stress, the results from FEM method conformed well with field measurement, some conclusions drawn from the design and construction Mil be valuable for future construction in similar engineering.
