Conference proceedings 2018s cover planning, design, modeling, monitoring and construction aspects of these essential structures. This volume is part of the proceedings of the 1st GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2017..

Inflammation

,Ausgewählte Kapitel der Elastostatik,evidently reduce the disturbance effect on surrounding rock, decrease the settlements of ground. Compared with CRD method, Double-heading construction method has advantages in utilizing the self-supporting ability of surrounding rock and supporting ability of preliminary lining, and also improving safety margin of the second lining.

Dysarthria

Analysis of Construction Scheme for Neighborhood Metro Tunnels with Two Different Inner Sections,evidently reduce the disturbance effect on surrounding rock, decrease the settlements of ground. Compared with CRD method, Double-heading construction method has advantages in utilizing the self-supporting ability of surrounding rock and supporting ability of preliminary lining, and also improving safety margin of the second lining.

Maßsynthese von Koppelgetriebenwas performed to evaluate the surface deformations. Using the superposition approach, the empirical data have been compared with the analytical results. The results confirm that there is a clear difference in the amount and distribution of ground movements with varying tunnel positions.
