Subject source: Sichuan Provincial Department of Education
Summary: Layered geotechnical problems under complex loads are a large number of geotechnical problems and engineering problems in the structural design and construction of slope engineering, underground engineering, tunnel engineering, water conservancy engineering, foundation engineering, road engineering, construction engineering, mining engineering, nuclear waste storage and other projects. With the massive construction of infrastructure, problems related to geotechnical engineering have become increasingly prominent. Related projects are affected by the deformation, strength and destruction of layered rock and soil under complex conditions, which often cause various geological disasters and engineering disasters such as tunnel collapse, landslide, debris flow, excessive deformation of building foundation, foundation inclination, surface subsidence, dam break, building cracking, mine pressure appearance and so on.
The research results of this project were completed by Dr. Liuli, a professor at xihua university Institute of Geotechnical Engineering, and it is an excellent scientific research project of the Ministry of Education. Starting from studying the complex mechanical properties of rock and soil, such as stress, strain, strength, constitutive relation, failure characteristics, construction technology and engineering application, this project has solved various technical problems and key control technologies in the process of rock and soil design, construction and operation under complex load and multi-factor coupling, and is an important technical means in various geotechnical engineering survey, design, construction, operation and maintenance projects. It can play an important role in solving practical technical problems such as tunnel engineering, slope engineering, underground engineering, foundation and foundation engineering, road engineering, river bank engineering, power machine foundation and foundation engineering, mine engineering, nuclear waste storage and so on, speeding up the project progress, reducing the project cost and ensuring the safety of production and operation.
Technical level: this project focuses on the theoretical and technical problems of geotechnical structures, especially layered geotechnical structures, due to multi-factor coupling and complex loads during the construction and operation of various modern projects. It combines micro, meso and macro methods, constitutive model and computer three-dimensional numerical analysis, modern geotechnical mechanics and engineering theory, advanced experimental methods and field monitoring technology, which highlights the combination of theory and practical application and forms a new theory, construction technology and engineering system to solve problems. For example, the world's first high hyperbolic arch dam "Study on the rock mass structure, damage and deformation mechanism of Jinping high slope and its relationship with the actual effect of slope engineering stability" has passed the technical appraisal organized by Sichuan Safety Supervision Bureau, and the expert appraisal conclusion is that the overall research results of the project have reached the domestic advanced level. And won the Science and Technology Award of China Society of Rock Mechanics and Engineering (certificate number: 2008YK-03-02-J02) authorized by the Ministry of Science and Technology of China, which created good economic and social benefits for the actual project. In addition, the project is also applied to the analysis of dynamic compaction subgrade engineering of Du Wen Expressway and some tunnels and subway projects, and published nearly 10 research results and application papers.
Application prospect: The research results of this project can be applied to engineering design and construction projects such as road engineering, slope engineering, underground engineering, tunnel engineering, foundation engineering, water conservancy engineering, construction engineering, mining engineering, nuclear waste storage and so on. It plays an important role in solving geotechnical engineering problems, speeding up construction progress, reducing engineering costs, promoting economic rationality, ensuring technical reliability and production and operation safety.
Second, the special foundation (deep foundation) experimental study
