UNDERGROUND FORECAST

THE ARTICLE PROPOSES A HYPOTHESIS FOR THE FUTURE DEVELOPMENT OF TUNNELLING IN THE WORLD. THE HYPOTHESIS IS BASED ON STATISTICS ON THE EXTENT OF TUNNELLING CARRIED OUT IN SIXTEEN INDUSTRIAL COUNTRIES. THE STATISTICS COVER TUNNELS WITH A CROSS SECTION OF MORE THAN TWO SQUARE METRES EXCLUDING MINING. AN ESTIMATE IS MADE OF THE WORLD POPULATION IN THE YEAR TWO THOUSAND AND A COMPARISON MADE OF THE TOTAL VOLUME OF TUNNEL DEVELOPMENTS IN THE SIXTEEN INDUSTRIAL COUNTRIES FROM 1960 TO 1970. THE PER CAPITA VOLUME OF TUNNEL CONSTRUCTION IS ALSO WORKED OUT. IT IS ESTIMATED THAT AT THE END OF THIS CENTURY TUNNELLING WILL HAVE A VOLUME THAT IS FOUR OR FIVE TIMES LARGER THAN AT PRESENT. THE TUNNELLING IN DEVELOPING COUNTRIES IS EXPECTED TO GROW FROM A FRACTIONAL PART OF THE VOLUME OF TUNNELLING IN INDUSTRIAL COUNTRIES, AS AT PRESENT, TO A VOLUME CORRESPONDING TO HALF OF THAT OF THE INDUSTRIAL COUNTRIES AT THE END OF THE CENTURY. IT IS SUGGESTED THAT EXPERIENCE AND KNOWLEDGE OF TUNNELLING IN URBAN AREAS SHOULD BE MADE AVAILABLE FOR FUTURE PLANNING IN BOTH INDUSTRIAL AND DEVELOPING COUNTRIES.
