The "Jiangsu Digital Underground Space Engineering Research Center", led by the Jiangsu Geological Survey and Research Institute and jointly applied with Nanjing University of Technology, has recently been approved for construction by the Jiangsu Provincial Development and Reform Commission. This marks a higher engineering technology innovation and research platform in the field of digital construction and intelligent empowerment of underground spaces, which will effectively promote the development of related majors and industries.
For over a decade, Jiangsu Geological Survey Institute has been continuously cultivating underground resources and has carried out investigations, evaluations, and digital construction of underground space resources and various types of special underground space resources such as granite, salt caverns, and karst in more than ten cities in Jiangsu Province. It has achieved fruitful results in ensuring scientific planning, safety construction, and intelligent management of underground space resources.
The underground space is located in a geological environment, and the geological structure has a significant impact on the development and utilization of the underground space. Jiangsu Geological Survey Institute obtains various attribute data information of geological bodies through exploration, geophysical exploration, testing, monitoring and other means. By using three-dimensional geological structure modeling to reveal the distribution and spatial changes of strata, fault structures, aquifers and aquifers, it has formed a digital stratigraphic construction technology system of "standard layer establishment intelligent assisted division multi element fusion multi-scale modeling visual interaction automated updating", and constructed a digital geological construction technology system The automated monitoring network for groundwater and ground subsidence cracks throughout the province has achieved a comprehensive and three-dimensional display of the geological structure and dynamic real-time monitoring of the geological environment, making underground spaces more transparent.
The current development status of underground space is another key factor that affects the safety construction of underground engineering beyond geological conditions. Jiangsu Geological Survey Institute obtains information on the current status of underground space development and utilization by establishing a survey path of data collection and organization, survey and mapping, geophysical exploration, and 3D laser scanning. It explores the applicability of methods under different geological elements, spatial scales, and complex urban noise conditions, and develops technology for constructing different types of current 3D models of underground pipelines, underground buildings, and other structures, Carry out the first detailed investigation and modeling of underground pile foundations in Suzhou, supporting underground space planning, site selection, and construction, and safeguarding urban safety.
