Abstract

Consolidation and contact Injection is a method by which the injection material is injected into pores, joints and cracks or cavities of rock and soil formations and improves the characteristics of the formations of soil and rocks, so that the permeability of the layers is low, resistance layers increase and their ductility decreases. Pooneh twin tunnels in the Arak-Khorramabad freeway have been weakened due to being under the groundwater level or due to explosions to dig the tunnels, which resulted in problems of water penetration into the body of the tunnel. In this paper, the optimization of the consolidation and contact injection process in the Pooneh twin tunnel project has been studied. In this project, by using contact and consolidation injection methods in the injection holes and optimizing the slurry mixing plan, water penetration into the tunnel is prevented so that parts of the body and crown of the tunnel are sealed.
