First, the apartment building was constructed. Then the plan called for an underground garage to be dug out. |
|
The garage was being dug on the south side, to a depth of 4.6 meters. |
|
The excavated dirt was being piled up on the north side, to a height of 10 meters. |
|
The building experienced uneven lateral pressure from south and north.
Heavy rains resulted in water seeping into the ground. The building began to shift and the concrete pilings were snapped due to the uneven lateral pressures. The building began to tilt. |
|
This resulted in a lateral pressure of 3,000 tonnes, which was greater than what the pilings could tolerate. Thus the building toppled over in the southerly direction. |
|
And thus came the eighth wonder of the world. |
|
If the buildings were closer together there would also have been a domino effect. |

They built 13 stories on grade, with no basement, and tied it all
down to hollow pilings with no rebar. Brought to you by the same folks that make your kids' toys and want to build your next car. |
