Question

Why is the leaning tower of pisa leant over?

Answer 1

THE PEOPLE WHO BUILT THE TOWER OF PISA, THEY DIDN'T HAVE THE TECHNOLOGY THAT WE HAVE NOW. ALSO TO ADD, THEY SAY WHILE IT WAS BEING BUILT, A GUST OF WIND PASSED BY.

Answer 2

The tower is built on unsuitable ground for such a heavy and tall building. It is only about 6 feet above sea level and built on a riverbed. The underlying ground is made up of layers of sand and clay. The layers are not even and the weight of the building has compressed them. Because the layers are not even, as the ground has compressed, it has sunk more in some places than others.

Answer 3

bad engineering, it just never fell over. I think the ground were it was built was soft or something.

Answer 4

hehe, dodgie italian engineering, they did not make the ground strong enough to support the structore the footing were to shallow which lead to the building tipping over slightly, then they decided to add more cement to the base and its stoped tilting any further

Answer 5

because it was built by the contractors who built wembly ?

Answer 6

the ground is unstable an the Italian try to fix it with concrete

Answer 7

Faulty architecture.

Why hasn't it fallen over?

The fact that it took such a long time to build may be the main reason it hasn't fallen. Between the periods of construction the ground had time to settle and become compacted, making the foundations stronger. Another important factor is the material it is built from; the limestone and lime mortar are able to bend and resist the forces that would make other, more brittle rocks, crack.

Answer 9

subsidence. the ground is full of water and each time they tried to correct it it got worse. I believe now its rafted to stop further leaning and is now safe enough for the public to go inside.

Answer 10

i think its because of the ground which is going a bit appart...

Answer 11

Poor site selection.

Answer 12

because if it was straight upright it wouldn't be called the leaning tower.
