SOME PROBLEMS OF TUNNELLING IN DUBLIN BOULDER CLAY

DURING CONSTRUCTION OF A SEWER (4.8 KM LONG, 3.7 M IN DIAMETER) WITH A TUNNEL LINING OF READY-MIXED CONCRETE SEGMENTS, THE POSSIBILITY PRESENTED ITSELF OF EXAMINING SOME PROBLEMS RELEVANT TO THE CONSTRUCTION OF TUNNELS IN BOULDER CLAY. THE AUTHOR REPORTS ON PROBLEMS PRESENT IN THE TAKING OF UNDISTURBED SOIL SAMPLES AND MENTIONS DETAILED EXPERIMENTS FOR THE EVALUATION OF ALL RELEVANT SOIL CHARACTERISTICS AND SOIL COEFFICIENTS. THE COMPLETED TUNNEL WAS EXAMINED AND MEASUREMENTS TAKEN OF STRESS AND DEFORMATIONS IN THE TUNNEL LINING. REFERENCES ARE MADE TO SUITABLE METHODS OF TUNNEL LINING. THE COVERING ABSTRACT FOR THE CONFERENCE IS IRRD NO 306088.
