Abstract

Single-column continuous-curved-beam bridges are often used in earthquake-prone areas, but their design characteristics make it difficult to predict structural damage during an earthquake. A large-scale model of a single-column, continuous-curbed-beam overpass that was damaged during the Wenchuan earthquake was created and tested on a shaking table. After the pier suffered seismic damage it was repaired using a polyurethane cement and re-tested. The results of the study revealed that polyurethane cement repair can improve the structural performance of this type of bridge and is a valid new method for the quick repair of earthquake-damaged bridge piers.

聚氨酯水泥单柱连续梁桥抗震修复

单柱连续曲线梁桥常用于地震易发地区，但其设计特点使其结构破坏难以预测。一个在汶川地震中受损的单柱、连续路沿梁立交桥的大型模型被制作出来，并在振动台上进行了测试。在码头遭受地震破坏后，使用聚氨酯水泥进行了修复并重新进行了测试。研究结果表明，聚氨酯水泥修补可以改善此类桥梁的结构性能，是一种有效的地震损伤桥墩快速修复新方法。
