ABSTRACT

Although the deep foundation pit supporting project is a temporary construction structure, it needs more funds and takes up a long time. Once the supporting structure fails, it will cause great economic losses and adverse social impacts. Informatization is a scientific construction management method. It continuously obtains the dynamic information of foundation pit deformation from the process of foundation pit excavation, so as to judge the safety of the supporting structure and the stability of the supported soil, so as to modify and supplement the original foundation pit supporting design and ensure the success of foundation pit excavation and support. In the deep foundation pit excavation technology of high-rise buildings in cities, it is an important research direction in engineering deformation monitoring and information construction that how to monitor them with concise methods, appropriate precision and effective analysis and early warning means. This paper analyzes the information construction technology of deep foundation pit engineering from the angle of deformation control, hoping to bring some help to the safe and smooth construction of deep foundation pit engineering in China.
