Abstract

The anti-power of the leg of the steel arch support on tunnel constructions in low bearing capacity of ground is needed to be installed in order to support loads of the ground. In such case, the stress concentration on the ground acting on the leg of the steel arch support and local destruction of the natural ground of the leg are induced. This research is focused on the raising of the adhesion nature of the natural ground where the leg of the steel support was installed. Moreover, the effects of the wing rib support of the new steel arch support leg on controlling the subsidence of the measures were clarified.
