| 摘 要： | 四川雅沪高速公路高山庙大桥在施工完毕后,发现2-4跨桥位横向偏移,造成桩基发生裂纹甚至断裂,需要在不拆除大桥的前提下完成桥位桩基的纠偏与加固。通过对多个桥梁纠偏与桩基加固的方案进行反复探索与论证,总结出一套便捷、实用、经济的施工方法,成功地达到该桥梁纠偏与加固的目的。详细介绍了加固方案、施工技术措施以及纠偏效果。

| Abstract: | The lateral shift was found in the 2-4 spans of a bridge position with cracks even fracture after a bridge construction and rectification and consolidation must be made without demolishing the bridge. By research and demonstration on schemes of bridge rectification and consolidation, a group of convenient, practical and economic construction method was summed up. The paper introduced the consolidation scheme, construction technical measures and rectification effect. |
