Failure in Shanghai Construction

5:30am, 27 Juni 2009 Lianhuanan, distrik Minhang kota Shanghai, China.
Failure caused by Soil Excavation

1. An underground garage was being dug on the south side, to a depth of 4.6 meters
2. The excavated dirt was being piled up on the north side, to a height of 10 meters
3. The building experienced uneven lateral pressure from south and north
4. This resulted in a lateral pressure of 3,000 tonnes, which was greater than why the pilings could tolerate. Thus the building toppled over in the southerly direction.

First, the apartment building was constructed

Then the plan called for an underground garage to be dug out.
The excavated soil was piled up on the other side of the building.

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.

And thus came the eighth wonder of the world.

Dampak dari pekerjaan galian tanah yang asal-asalan itu bisa luar biasa.
Agar tidak terjadi kesalahan lagi, belajarlah dari kesalahan yang pernah terjadi.
