터널굴진율이 막장에서의 침투력에 미치는 영향에 관한 연구
Effect of Tunnel Advance Rate on the Seepage Forces Acting on the Tunnel Face
초록
In this study, the effect of tunnel advance rate on the seepage forces acting on the tunnel face was studied. The finite element program to analyze the groundwater flow around a tunnel with the consideration of tunnel advance rate was developed. Using the program, the parametric study for the effect of the tunnel advance rate and hydraulic characteristics of the ground on the seepage forces acting on the tunnel face was studied. From this study, it was concluded that the tunnel advance rate must be taken into consideration as an additional parameter to assess the seepage forces at the tunnel face and a rational design methodology for the assessment of support pressures required for maintaining the stability of the tunnel face was suggested for underwater tunnels.
