Research on Damage Repair and Reinforcement of Deep Foundation Pit Support Structure Based on Fractal Dimension Theory

Foundation pit engineering refers to the excavation in the ground below the underground space and its supporting support system. The foundation pit support is used to ensure the excavation of the foundation pit, the smooth construction of the foundation and the safety of the surrounding environment. The support and reinforcement measures are also used for the side wall safety of the foundation pit and the surrounding environment. With the rapid development of China's high-rise buildings, deep foundation pit support is the current construction of a wide range of important applications. This has a direct impact on the safety and quality of construction. Therefore, it is of great significance to strengthen the research on the damage of deep foundation pit support. This paper introduces a kind of repair and reinforcement of deep foundation pit support which is based on fractal dimension theory. According to the complex environmental effects of foundation pit engineering, the reinforcement of foundation pit support should not only ensure the safety and stability of the foundation pit itself, but also effectively control the movement of the surrounding strata and protect the surrounding environment.
