Research interests

Dynamics of rock and soil mass. Study the dynamic properties and response of rock and soil under dynamic load, including the type and characteristics of dynamic load, dynamic strength, dynamic deformation and dynamic pore water pressure of rock and soil, dynamic constitutive model of rock and soil, dynamic response analysis and dynamic stability analysis of rock and soil, and recognize the ground caused by earthquake, blasting, dynamic compaction, traffic vehicles and other industrial vibration sources Characteristics and response of surface vibration and its effect on engineering. Welcome students majoring in geotechnical engineering, geological engineering, engineering mechanics, solid mechanics, etc. to apply for postgraduate examination.
