[0002] In urban construction, the construction of underground structures is an indispensable part, which includes the construction of basements of high-rise buildings, subway tunnels and other underground facilities. In order to ensure the safety of these construction activities and the stability of the surrounding environment of the foundation pit, effective support, reinforcement and protection measures must be implemented on the side walls of the foundation pit and the surrounding environment. These measures are crucial to maintaining the safety of important facilities such as traffic arteries, existing buildings and underground pipelines around the foundation pit.

[0003] In dense urban environments, the excavation of deep foundation pits is particularly complex because they are often surrounded by various structures, such as roads, buildings, and pipelines. The existence of these structures places higher demands on the safety of foundation pit projects. In order to meet these requirements, and to shorten construction periods and reduce costs, the steel truss structure system with a beam string has been widely used in foundation pit support projects due to its excellent mechanical properties and economy.

[0004] However, although the beam-string steel truss support scheme is efficient in theory, in actual operation, after the finite element calculation, a series of tedious data post-processing work is required, including data analysis, verification, collation and report output. These tasks are not only time-consuming and labor-intensive, but also prone to errors, which seriously affects the efficiency and safety of the project. At present, there is a lack of an effective method on the market that can automatically and quickly process these data and generate a complete analysis report.
