病害桥墩荷载试验与加固设计

Loading Test and Reinforcing Design of Disease Bridge Pier

该文介绍了同三线上某桥梁的检测及荷载试验情况。通过检测及荷载试验对桥梁进行了测试,实测了应变、挠度及裂缝响应等。根据试验结果对桥墩盖梁及墩身开裂的原因进行分析计算评价,据此提出了针对病害盖梁和墩身的加固设计方案。

The article introduces the inspection and the loading test conditions of a bridge on Tangsan Line. Through the inspection and the loading test, the article testes and measures the strain, deflection and crack response of the bridge. Based on the test result, the article analyzes, calculates and evaluates the cracking reasons of the pier cover beam and the pier shaft. The article puts forward the reinforcing design scheme for the disease cover beam and the pier shaft accordingly.
