摘要
提出一种由钻孔勘探、跨孔CT、化学分析相结合的方法综合评估灌浆加固后的水泥用量大小。以贵州某桥固结灌浆加固工程为试验对象,将此方法的评估值与实际水泥用量进行对比。结果表明其误差较低,评估效果良好。
This paper presents a comprehensive evaluation of the amount of cement after grouting with a combination of drilling exploration,cross hole CT and chemical analysis. The consolidation grouting reinforcement project of a bridge in Guizhou is taken as a test object,and the evaluation value of this method is compared with the actual cement content. The results show that its error is low and the evaluation results are good.
