The stress state of underground tunnels and galleries evolves over time , firstly because of the advancement of the working face during construction , then due to gradual changes in soil properties and mechanical properties of materials component of the infrastructures (reduction of cohesion, aging). These changes are caused by combined actions such as: weathering processes due to infiltration of meteoric waters and concessionaires networks, but also by the cracks appearance that induce further redistribution of stress and strain, and the creep. A particular attention is paid to the determination of the initial state of stresses applied on the structure right after the construction. In order to approach this initial stress state which corre...
