Abstract
In this study, the stability of concrete in foundation pit support is systematically discussed by deeply analyzing the basic principle of foundation pit support technology and the characteristics of concrete materials. The basic theory of foundation pit engineering is summarized, and the characteristics of high compressive strength and durability of concrete materials are analyzed in detail, which provides theoretical support for stability analysis. From the geological condition, the shape of foundation pit, the size of foundation pit and the construction technology, this study comprehensively analyzed the influence of these factors on the stability of concrete foundation pit support. Through empirical study and case analysis, it is revealed that the displacement of supporting structure, piping and sand flow, collapse risk and material quality problems are the main challenges faced by concrete in foundation pit support. In order to deal with these challenges, this study proposes a series of targeted strategies. By enhancing the design and construction of the supporting structure, optimizing the drainage system to reduce the risk of piping and sand flow, implementing an effective monitoring and early warning mechanism, and strictly controlling the quality of supporting materials such as concrete, this study provides a practical solution for improving the stability of the concrete foundation pit support. It also emphasizes the importance of environmental protection and sustainable development in foundation pit support engineering, and advocates the use of environmentally friendly materials and green construction technology to reduce the impact on the environment. This study aims to provide theoretical support and practical guidance for the safe construction and sustainable development of foundation pit engineering by deeply analyzing the stability of concrete in foundation pit support and its influencing factors, and putting forward effective countermeasures.
