建筑物裂缝是一个带有普遍性的技术问题,虽然结构设计是建立在强度的极限承载力基础上,但大部分工程的使用却是由裂缝控制的。结构的破坏和倒塌也是从裂缝扩展开始的,所以人们对裂缝往往产生一种破坏前的恐惧感。但是,建筑物的裂缝是不可避免的,裂缝是一种人们已经可以接受的材料特征,科学的要求应该对其有害程度控制在允许范围值内。本文论述了民用建筑地基差异性沉降裂缝的形成与控制问题。 Building cracks are a common technical problem. Although the structural design is based on the ultimate strength of strength, most of the works are controlled by cracks. Structural destruction and collapse also begin with the expansion of the cracks, so people tend to produce a pre-destruction fear of cracks. However, cracks in buildings are unavoidable. Cracks are a material feature that people already accept. Scientific requirements should control their harmfulness within the permissible range. This article discusses the formation and control of differential subsidence cracks in civil buildings.
