Biography of Professor RAO Qiu-Hua:

PhD from Lulea University of Technology in Sweden, second-class professor of Central South University, member of Chinese Society of Rheology (CSR)，executive director of the Deep Energy Storage Branch of the Chinese Society for Rock Mechanics & Engineering, vice chairman of the Hunan Society of Theoretical and Applied Mechanics. She has been long engaged in research on the theory and application of rock and soil rheology, damage and fracture, based on the forefront of the disciplinary development and the major strategic needs of the country. In the field of deep-sea mineral resource exploitation, she established a multi-directional static/dynamic nonlinear rheological constitutive theory for deep-sea soft soil, and proposed a calculation method for the traction force of the mining vehicle during its straight/turning/obstacle crossing operations based on the rheological properties of deep-sea soft soil and a multi-objective optimization method for the tooth structure of mining vehicle based on the principles of high performance, low disturbance and lightweight. This findings provides an important guidance for the development of green and efficient deep-sea mining equipment. In the construction of heavy haul railway subgrade, she proposed a prediction method for the viscoelastic parameters of multi-layer coarse-grained soil with consideration of the interface layer and actual pebble inclusion shape, and established a coupled constitutive theory of the interface damage-creep-fatigue to predict the creep-fatigue interaction deformation of the multi-layer coarse-grained soil for providing an important basis for the stability design and safety assessment of the heavy haul railway multi-layered subgrade. She has led over 20 scientific research projects at the national, provincial and ministerial levels, as well as at the enterprise level. She led the organization of the First National Youth Academic Forum on Geotechnical Rheology and Engineering Safety (2022, chairman of the organizing committee) and assisted in organizing the 4th Pacific Rim Conference on Rheology (PRCR4, 2005, secretary general).
