A 12 STORY BUILDING IN CHINA LYING ON THE GROUND

(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 tons, which was greater than what the pilings could tolerate. Thus the building toppled over in the southerly direction.
