Abstract：The settlement control of adjacent building is a critical issue in foundation pit construction. The impacts of the construction of both three-axis high-pressure rotary jet grouting piles and diaphragm wall on a historical building in a subway station of Tianjin were analyzed based on the real time monitoring data，focusing on the effect of trench construction of diaphragm wall on the adjacent building settlement. The settlements in the retaining structure construction phase，the foundation pit excavation phase and the whole construction period were compared，to explore the impacts of three-axis high-pressure rotary jet grouting piles retaining structure and diaphragm wall on the building settlement. The reasons for building settlement caused by different retaining structure forms were emphatically analyzed and settlement control methods were proposed for building protection. The results obtained could provide reference to similar projects.
