摘要
为了研究加筋土挡土墙的破坏机理和加固技术,以某立交桥挡土墙加固工程为例,首先分析了加筋土挡土墙的失稳原因,采用了喷射混凝土、预应力锚杆、注浆联合加固方案,然后对施工中的主要技术难题进行研究并提出了解决方案,最后用国际流行的软件FLAD2D进行数值模拟.加筋土挡土墙加固后预应力稳定,墙面无变形,表明联合加固方案是可行的.
In order to study the failure mechanism and reinforcement technique of reinforced earth retaining walls, the reinforcement project of a crossroad was taken as an example. The failure mechanism was analyzed firstly. A united measure of shotcrete lining on the surface, pre-stressed anchor and injection was applied. Main problems in construction were discussed and solved. Lastly, the reinforcement effect was simulated with FLAC^2D. After the reinforcement, stable stress and little deformation indicate the united measure is effective.
