How can we... save our past and protect our future? We should be proud of our civilisation today, and its many great achievements. But which of the great achievements of yesterday are so important to our sense of history? By applying the latest technology, civil engineers can save structures and monuments from the distant past so that they can still be enjoyed well into the future. And what of tomorrow? What are we doing today that will provide enjoyment and education for generations to come? Civil engineers are using designs and materials that will protect our natural and cultural heritage for future generations.
The Leaning Tower of Pisa save our past and protect our future Construction on this Italian tower originally began in 1173 and continued for over 200 years. Built on very soft ground, the tower first started to lean whilst it was being built, and by 1990 it was on the point of falling over. To make matters worse, forces within the stonework of the tower were so great that it might have actually exploded outwards. The Italian government brought together a team of experts to save their historic monument. Not surprisingly, civil engineers were an important part of the team. Before touching the tower itself, the engineers made a virtual computer model of it, which accurately shows how it has leaned over time. The virtual model was used to work out a way of making the tower more stable. Rather than trying to prop up the tower above ground, which would have been unsightly and dangerous, the engineers worked out a method of removing soil from beneath the foundations. This solution gently reduced the tower’s lean by about half a metre and rescued it from destruction. Their tower saved, Italians will be able to take pride in this national treasure for generations to come. Find out more at http://torre.duomo.pisa.it/index_eng.html Photography: Getty Images
