介绍了湿陷性黄土路基劈裂注浆的加固机理,着重从水灰比、浆材掺量进行试验研究,确定出合理浆液配合比,并将其应用到实际工程中,同时用不同检测方法对比,分析注浆效果,并提出了注浆加固中有待解决的问题。 The reinforcement mechanism of collapsible grouting in collapsible loess subgrade is introduced. The research on the ratio of water - cement ratio and pulp content is emphatically carried out. The proportion of reasonable grout is determined and applied to practical engineering. At the same time, In contrast, the grouting effect is analyzed, and some problems to be solved in grouting reinforcement are put forward.
