【Abstract】 There are two buildings which are both separated into two units by settlement joint. It’s found that the two units were leaning opposite to each other. The width of settlement joint of one building was enlarged by reducing the width of upper walls and the other building was rectified by statically jacked piles with anchor bars, so that the two units will not contact at the top. The general situation and deformation of foundation of the two buildings are introduced.The reasons inducing the two buildings to contact at the top are preliminarily analyzed.更多还原
