已有土体劈裂注浆加固机理方面的研究成果多是定性结论,并未明确区分注浆挤密作用、浆脉骨架作用对于被注土体强度的影响,针对上述问题,自主设计了室内注浆加固试验系统;通过室内注浆试验与数值分析研究了注浆挤密作用、浆脉骨架作用对于注浆加固效果的影响规律,获取了土体劈裂注浆加固主控因素。 The research results on the mechanism of splitting and grouting of soil have mostly been qualitative conclusions, and the effect of grouting and grouting and the role of the slurry-skeleton on the strength of grouted soil has not been clearly distinguished. In response to the above problems, the interior design Grouting reinforcement test system. The effects of grouting and grouting and the effect of slurry skeleton on the grouting reinforcement effect were studied by indoor grouting test and numerical analysis. The main controlling factors of grouting and grouting reinforcement were obtained.
