| Abstract: | The existing bridge requires high strengthening technology and has great difficulty in construction. Based on the condition analysis for bridge, the integral rigidity and stability of the bridge were greatly improved by the Banshen railway bridge reinforcement with outside professing and stick steel strengthening method, new materials of low anchorage and poly-mer concrete, which achieved good effects. This article briefly introduced crack treatment techniques and planting bar tech-niques. |
