Deep foundation pit support is a commonly used technology to improve the foundation stability of high-rise building engineering,and the construction is difficult.In order to ensure the sufficient support in the construction,this paper analyzes the deep foundation pit support technology in combination with the actual project of the high-rise building engineering,determines the support scheme according to the actual situation of the engineering,and focuses on the analysis of technical points such as support piles,cement mixing piles,dewatering and drainage treatment.The monitoring of the foundation pit proves that there is no alarm phenomenon in the monitoring values of the foundation pit after the construction,and the support effect is ideal,hoping to provide useful technical experience for the same type of engineering.
