砂砾石注浆在某水库1号桥基础加固中的应用

Application of Guouting Technique on Sandy Gravel Stratum to Reinforce Abutment of No.1 Bridge in a Certain Reservoir

某水库1号桥位于库区内,水库蓄水后一段时间,左岸桥台基础产生不均匀沉降,根据分析,最终采用砂砾石注浆技术对该桥台基础加固,由目前观测资料来看,未发现该桥台继续下沉,这表明砂砾石注浆加固效果较好。

The No.1 bridge is located within a certain reservoir. In the bridge's left bank abutment foundation, the uneven settlement occurred after water was stored in this reservoir for a few days. According to the analysis, finally the grouting technique in the sandy gravel stratum to reinforce the bridge foundation was adopted. In light of the present observation data, it is not found that the bridge continues to sink, and it shows that the effect of the grouting reinforcement technique is better.
