Failure in Shanghai Construction

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.

sina1
First, the apartment building was constructed
sina2
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.
sina3
Heavy rains resulted in water seeping into the ground.
sina4
The building began to shift and the concrete pilings were snapped
due to the uneven lateral pressures.
sina5
The building began to tilt.
sina6
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.
