相邻的新旧建筑物潜在的工程事故是新建筑物的荷重在地基中新增加的附加应力 ,引起旧建筑物地基产生过大的不均匀沉降 ,从而导致旧建筑物的破坏。当新建筑物有相邻旧建筑物时 ,必须注意结构设计中的相互影响问题 ;当新建筑物自身刚度较好 ,地基浅层无软弱土层时 ,以局部桩基处理相邻新旧建筑物的相互影响是一种可靠的方案 The potential engineering accidents of adjacent new and old buildings are the additional stress added by the new building’s load in the foundation, causing excessive uneven settlement of the foundations of old buildings, resulting in the destruction of old buildings. When adjacent buildings are adjacent to old buildings, attention must be paid to the mutual influence in the structural design; when the new buildings themselves are relatively rigid and there is no soft soil layer in the shallow foundation, adjacent old and new buildings are treated with local pile foundations. The mutual influence is a reliable solution
