Core Viewpoint - The establishment of the Shield Tunnel/Boring Machine (TBM) Big Data Mining Community in Zhengzhou marks a new phase of data-driven, intelligent, and standardized tunnel construction in China [1] Group 1: Industry Development - China's tunnel construction has developed rapidly, with an average of over 4,000 kilometers of tunnels completed annually in the past five years, leading the world in total scale of tunnels under construction and in operation [1] - The country has become the largest global producer of TBM equipment, with 661 units produced in 2023, widely applied in various tunnel construction projects and exported to about 40 countries and regions [2] Group 2: Technological Advancements - TBM has become the mainstream method for tunnel construction due to its safety, quality, and efficiency compared to traditional methods [2] - The rapid development of new information technologies such as artificial intelligence, cloud computing, and big data has increased the demand for data-driven and intelligent requirements in tunnel construction [2] Group 3: Community Objectives - The Shield/TBM Big Data Mining Community aims to address challenges such as fragmented data mining technology and lack of unified standards by promoting data interconnectivity and breaking down "data silos" [2][3] - The community will focus on three core tasks: building a unified data center, collaborating on technical challenges, and deepening integration between industry and research [3] Group 4: Innovations in Tunnel Construction - The launch of the "Pioneer Tunnel Big Model," the first vertical big model in the tunnel and underground space sector, coincides with the establishment of the community [4] - The trend towards "green and low-carbon, intelligent and efficient" tunnel construction is becoming increasingly evident, with the new model enabling real-time detection of complex geological conditions, achieving a prediction accuracy of over 90% in certain scenarios [4]

Core Viewpoint - The establishment of the Shield Tunneling Machine (TBM) Big Data Mining Community in Zhengzhou marks a significant step towards data sharing and collaboration in the tunneling industry, addressing current challenges such as fragmented data technology and lack of unified standards [1][2]. Group 1: Establishment and Objectives - The Shield/TBM Big Data Mining Community was founded on August 10, attracting over 400 representatives from more than 160 domestic units [1]. - The community aims to break down "data silos" and create a new intelligent ecological paradigm for the industry [1]. - Three core tasks have been identified: building a unified data center, collaborating on technical challenges, and integrating production and research to accelerate technology transfer [1]. Group 2: Technological Advancements - The "Pioneer Tunnel Model" was released, which is the first vertical large model in the tunnel and underground space sector, facilitating a shift from traditional experience-driven methods to data-driven intelligent decision-making [1]. - The model has achieved over 90% accuracy in predicting complex geological conditions, such as faults and sinkholes, enhancing safety and efficiency in tunnel construction [2]. - The new intelligent feedback technology system has been validated in projects like the plateau railway tunnel and the Chongqing-Taiwan Yangtze River Tunnel, promoting safe, high-quality, efficient, and green tunneling practices [2].
