摘要
针对京福铁路客专闽赣Ⅱ标段临湖特大桥30、31号桥墩下复杂的岩溶特点,通过反复研究论证,确定了压力注浆预加固溶腔充填物的地基处理方案。并对该方案实施工程中施工工艺、注意事项以及后期质量检测做了详细介绍,可为今后类似工程提供一些参考。
According to the complex karst characteristics near No. 30 and 31 piers of the large bridge at Beijin -Fuzhou passenger dedicated line and by the repeated discussions, the foundation treatment plan was decided to take pre-reinforce- ment of dissolved cavity fillings by pressure grouting. The paper introduces the construction processes, attentions and late quality detection, which can be the reference to the similar engineering.
