An　innovative　concrete　reinforcing　technique　of　prestressed　high　strength　steel　wire　(steel　wire　rope)　mesh　(PSWM)　is　presented.　Approximate　full-scale　tests　of　24　concrete　circular　columns　strengthened　with　PSWM　and　2　contrast　columns　were　put　forward　to　research　the　strengthening　effects　of　main　experimental　parameters　of　the　steel　wire　spacing　and　the　prestressing　level　of　steel　wire　under　axial　loading.　The　test　results　show　that　the　peak　stress　and　strain　of　the　strengthened　columns　are　83%　and　95%　greater　than　those　of　the　contrast　columns.　By　raising　the　steel　wire　prestressing　level,　the　reinforcing　effect　is　improved;　with　steel　wire　spacing　decreased,　strengthening　effect　is　greatly　improved.　The　formula　of　peak　stress　&　strain　and　2　kinds　of　stress-strain　full　curve　relationship　models　of　the　columns　strengthened　with　PSWM　were　proposed.　The　calculated　results　agree　well　with　the　experimental　ones　and　a　theoretical　support　for　related　research.　The　presented　technology　is　an　attractive,　nondestructive,　and　efficient　reinforcement　technology,　worthy　of　popularization　and　application.
