With the continuous development of urbanization and subway tunnel engineering, more and more overlying projects are constructed near the existing subway tunnels. Therefore, the grouting reinforcement of the subway tunnel soil layer has become more and more important, and the grouting effect has also received more attention. Based on the tunnel project of Zhengzhou East-Boxue Road Station in Zhengzhou City, this paper uses the numerical simulation method to compare and analyze the influence of grouting aperture, grouting pressure on the grouting effect of subway tunnel. The results show that with the expansion of grouting aperture, the grouting effect is continuously enhanced, but after reaching a certain degree, it will slowly increase; with the increase of grouting pressure, the grouting effect in the early stage increases with the increase of pressure, and will remain a certain value in the later stage.
