Personal statement

Li Pengfei, Professor and Doctoral Supervisor, College of Architecture and Civil Engineering, Beijing University of Technology. His research interests mainly focus on the stability of surrounding rock and mechanical properties of support structure for tunnels in the saturated ground. He has presided 3 NSFC projects and 2 BJNSF projects. The space-time effect of ground displacement was investigated, and failure modes of tunneling face were proposed, then analytical solutions of ultimate pressure were obtained. Ground reaction curves and analytical solutions of seepage field for deep tunnels in the saturated ground were deduced with considering the effect of ground reinforcement. Pore-water pressure distribution conditions in the composite linings were revealed, and the quantitative relation between water pressure and seepage discharge was explored, and then a design method was given to acquire a reasonable grouting circle. A maintainable proof-drainage system and a bottom water pressure reduction drainage system were invented, and their corresponding model testing installations were developed. Acting modes and calculation models of surrounding rock pressure for parallel tunnels with a small clear distance were illuminated, and a physical testing appliance of twin tunnels was devised. He has published more than 70 papers and one academic monograph, obtained more than 30 authorized invention patents, and won 7 provincial-level scientific and technological progress awards.
