| Abstract: | To increase the bearing capacity of Shizhu-Huanglong Bridge and enable it to meet the requirements of road-II load,the current technical state and bearing capacity of this bridge are evaluated through the full inspection,load test and finite element analysis.On this basis,the comprehensive technology is used in reinforcement design,such as reinforced concrete confining and high pressure grouting.After more than two years running,the good strengthening effect of this bridge has been proved. |
| Keywords: | stone arch bridge strengthening load test bearing capacity reinforced concrete confining high pressure grouting |
