Analysis of the Stress and the Deformation Characteristics of the Initial Support of the Large Section deeply buried in the sandy loess tunnel

To explore the stress and deformation characteristics of a large section that deeply buried in the sandy loess tunnel structure, numerical simulation and field test analysis were carried out and the initial support structure of sandy loess tunnel was studied based on the Panxian Mountain Tunnel Project in Zhonglankezhuan. With field sand loess physical parameter and mechanical properties, a series...
