This project was led by Tongji University with the joint participation of multiple institutions. Relying on its "diaphragm wall construction big database" accumulated over more than 30 years, Shanghai Yuanyang provided foundational data support for the project's intelligent control module for retaining structure construction. The system systematically solved multiple industry technical problems, including the precise selection of trenching processes and equipment for diaphragm walls under complex geological conditions, the matching of geological conditions in different regions of China with slurry performance indicators and the mix proportions of slurry-making materials, the lack of data basis for relatively accurate calculation of trenching construction cycles, and the accurate selection of emergency response technical plans during construction under different geological conditions.
