Advance support is an effective anchoring method in the tunnel construction especially for the tunnels getting through the weak and broken rock mass. However, the supporting effectiveness can hardly be predicted due to the design which is mainly relying on experiences. In this paper, the supporting mechanism and theory of advanced small pipes used in worse geological tunnel is analyzed and numerical simulation has been done using FLAC3D for Hongshigou tunnel. Finally, the effectiveness and rationality of advanced small pipes technique is evaluated.
