劈裂灌浆加固技术现场试验研究

In-situ Tests Research to Anti-seepage Reinforcement Technology of Splitting Grouting

针对该技术在施工过程中对坝体的稳定性影响,结合某水库大坝防渗加固工程,开展了大量的现场试验研究。通过现场试验研究,得到了劈裂灌浆施工工程中坝体的沉降变化规律,总结了孔隙水压力以及浆脉形成情况,评价了劈裂灌浆效果,为现场施工提出了理论指导和依据。

In this paper Combining engineering, a large number of in - situ tests were carried out in order to evaluate the effect of the dam＇s stability. Through the in - situ tests, the settlement rule of dam during reinforcement can be obtained. And the paper summarizes the variation of pore pressure and anti - seepage curtain. Furthermore, the effect of splitting grouting in this engineering is appraised based on those results. Those conclusions provide instruction to the construction of the splitting grouting reinforcement and reference to the popularization of this technique in this kind of engineering.
