Abstract Research purposes: Pile foundation substitution is a difficult problem in foundation work and the displacement controlling is the key to the pile foundation substitution works. This paper introduces briefly the foundation substitution works under the Grand Merchandise Building in Shenzhen metro, and emphasizes the analysis of the displacement controlling.
Research conclusions: The displacement controlling value is obtained, and the maximum internal force under this value is precondition for substitution structure and dynamic monitoring during constructing.
