 IT'S A 12 STORY BUILDING IN CHINAoN> LYING ON THE GROUND. 

(1) An underground garage was being dug on 

      the south side, to a depth of 4.6 metersoNVERTER>. 

(2) The excavated dirt was being piled up on

      the north side, to a height of 10 metersoNVERTER>. 

(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 what 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 tilt. Then it began

to shift and the *_hollow_* concrete

pilings were snapped due to the uneven lateral pressures 

And thus was born the eighth wonder of the world. 

If the buildings were closer together it would have resulted in a domino effect.
