摘要: This paper presents the results of laboratory and numerical investigations on deformation behaviour tunnel face reinforced with longitudinal pipes. A series reduced-scale model tests as well 3D finite-element analyses were carried out particular emphasis effects reinforcement parameters such density (number), length stiffness reinforcements behaviour. The present study indicate among other things that technique can significantly reduce not only but also ground surface settlements, suggesting reinforcing be effectively used a positive means for movement control during urban tunneling. illustrates effect is influenced by manner in which are distributed, there exists critical value each parameter from maximum derived. Implications findings this discussed great detail.
