GUO Feng-qi,YU Zhi-wu(School of Civil Engineering,Central South University,Changsha 410075,China)  
In this paper,combined with practical work,steel-concrete composite structure fitted with suspended net and self-compacting concrete is adopted for strengthening of stone arch bridges.By calculation and analysis,the method can greatly improve carrying capacity,rigidity and striking prevention ability of the strengthened structure and consequently upgrade the load and improve operation capacity of stone arch bridge.At the same time,it saves a lot of templates,solves the problem of difficulty in light-weight stone arch bridge bonded with steel,ensures the reinforcing effect and provides a new idea for stone arch bridge strengthening.
