一、注浆结石体强度研究的方法 用人工的方法向地层中颗粒间隙、土层的界面或岩层的裂隙注入具有充填、胶结性的注浆材料,其目的有二:一是对被注地层进行固结或加固,以增加其强度;二是对被注地层进行堵水防渗。这就是说,为了取得好的注浆效果,就应形成足够而有效的浆液固结体,使该固结体不但有足够的大小、密实度,还有足够的强度。
First, the strength of the grouting stone is studied by artificially injecting grouting material with filling and cementing into the particle gap, the interface of the soil layer, or the fracture of the rock layer in the formation. The purpose is twofold: First, the injected formation. Consolidation or reinforcement is performed to increase its strength; the second is to seal the impervious layer of the injected stratum. That is to say, in order to obtain a good grouting effect, a sufficient and effective slurry consolidation body should be formed so that the consolidation body not only has sufficient size, compactness, but also sufficient strength.
