| Abstract: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-reinforcement 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. |
