    Abstract
  • The design and construction of strengthening of a building in soft soil area is taken as an example. The reasons for the settlement and the inclination of this project are analyzed in combination with the monitoring data by the Third Party. Through the description of the design and construction of micro-pile reinforcement, some suggestions for the foundation treatment and consolidation in the soft soil area are provided. The reinforcement effect of micro-pile composite foundation is very good, which can effectively control the post-construction settlement. Besides, the construction technology is simple and economic. The results may provide references for the similar reinforcement and projects deflection rectification. Furthermore, they can supply guidance for the foundation treatment in soft soil area.
