Recently, at the 2024 Science and Technology Award Ceremony of the Chinese Society for Rock Mechanics and Engineering, the project "Key Technologies and Applications of Multi-source Precise In-situ Testing and Intelligent Analysis for Engineering Geology," led by the Fourth Survey and Design Institute of China Railway (CRFSDI), stood out from nearly one hundred innovative achievements and won the First Prize for Scientific and Technological Progress.

With the rapid development of high-standard, high-quality, and large-scale infrastructure construction in China, geotechnical engineering, which previously focused on stability control, has gradually entered a new stage centered on deformation control. In particular, millimeter-level deformation control standards for high-speed railways and underground projects in complex urban environments impose stringent requirements for the precise acquisition of geotechnical parameters.

The project team focused on the key technologies of "multi-source precise in-situ testing and intelligent analysis." Addressing shortcomings in theoretical analysis methods, testing technology and equipment, and intelligent fusion analysis for engineering geological in-situ testing, and relying on multiple National Natural Science Foundation projects, major domestic and international projects, and major research topics of China Railway Group, the team carried out nearly two decades of sustained research. It innovatively developed high-precision methods for obtaining in-situ deformation parameters of foundation soils, integrated in-situ testing technology and equipment for multiple scenarios, and an intelligent fusion analysis platform for multi-source heterogeneous data, overcoming the challenge of analyzing high-precision in-situ deformation parameters of foundation soils. The project results fill three industry gaps, include two sets of testing equipment that are the first of their kind in China, and achieve major technical indicators at the international leading level, strongly supporting refined design of infrastructure centered on deformation control.

The project results have been successfully applied to high-speed railways such as the Beijing-Shanghai and Wuhan-Guangzhou lines, expressways such as the Shenzhen-Zhongshan Link and the Dalian Bay cross-sea transportation project, urban rail transit in Hangzhou and Wuhan, and overseas projects such as the Malaysia East Coast Rail Link and the Padma Bridge in Bangladesh. They have withstood the test of time and practice and achieved significant economic and social benefits.

Sun Honglin, Deputy Chief Engineer of CRFSDI, introduces the project results

Sun Honglin, the project's principal investigator and Deputy Chief Engineer of CRFSDI, held in-depth exchanges and discussions with academicians and experts at the Science and Technology Innovation Forum of the Chinese Society for Rock Mechanics and Engineering. The innovative in-situ testing technologies and the development of the intelligent geotechnical parameter analysis platform achieved by the project received unanimous approval and recognition from the experts and scholars.

The Chinese Society for Rock Mechanics and Engineering is a national society under the leadership of the China Association for Science and Technology that undertakes the task of building a world-class society and brings together top scientific and technological innovation leaders in the fields of rock mechanics and geotechnical engineering in China. The society's Science and Technology Award includes the Natural Science Award, the Technological Invention Award, and the Scientific and Technological Progress Award. It is evaluated once a year through preliminary and final review stages. The First Prize for Scientific and Technological Progress is mainly awarded to research results with original innovation and major contributions to disciplinary development or national economic construction.

Digital and intelligent exploration, born for innovation. CRFSDI will continue to take leading industry technological innovation as its mission and refined detection and intelligent evaluation as its core goals, promote the development and progress of new in-situ testing and exploration technologies, and inject stronger new quality productive forces into the engineering survey industry.
