As one of the commonly used technologies in modern civil engineering, the construction technology is becoming more and more widely used with the continuous growth of building height. In the construction process of high-rise buildings, the deep foundation pit support provides the necessary stability for the foundation structure of the building project, and more effectively guarantees the quality of the project. Through the reasonable supporting structure, the deep foundation pit technology can effectively prevent the risk of soil collapse, foundation pit deformation and other risks, and improve the safety factor of the whole construction project. Especially in the high-rise buildings, the deep foundation pit support technology can consolidate the foundation for the long-term stability of the project, and significantly prolong the service life of the building. The continuous development of deep foundation pit construction technology is the inevitable demand of high-rise building construction, and also provides a powerful help for the development of civil engineering industry. Based on this, this paper focuses on the application of deep foundation pit construction technology in civil engineering construction.
