| 説明 | The leaning Tower of Pisa is the freestanding bell tower of the cathedral of the Italian city of Pisa. Famous for its unintended tilt, the 56m tower took nearly 200 years to build - work started in 1173. Five years later it started tilting and was noticeable as workers built the second floor. The shift was caused by shallow foundations of 3m and unstable subsoil. The tower was finally completed in 1372. Attempts were made throughout the tower's history to correct the tilt and some of them made the problem worse and by the 1990s there were fears the tower could collapse altogether. The Italian government appointed a 'committee of 13 experts' to come up with a plan to save the tower in 1990. The team was led by British engineering expert John Burland. |
