HE’s group developed an energy dissipation and seismic mitigation method to prevent the rock-fall hazard. The group also invented a new energy dissipation cushion structure and protective structure of rock retaining wall.
The research results have been successfully applied into the prevention of rock-fall in Yingxiu-Wolong Road, National Highway No. 213, and Chediguan Bridge. It’s proved that the research has made good progress in economic and social effects and will play more and more important role in protecting national security and people’s lives and property.
