地基发生不均匀沉降后,沉降较大的部位与沉降较小部位之间,基础底的地基表面产生局部凹陷。在局部凹陷处,基础失去了支撑而产生相对位移。上部荷载只能由砖砌体承担,则在砖砌体上产生了附加拉力和剪力,当该应力大于砖砌体的承载能力时,即会出现裂缝、裂缝多数出现在房屋下部,少数可发展到二层和三层。因此,本文主要针对因地基不均匀沉降引起的砌体裂缝问题进行详细的分析论述。 After uneven subsidence occurs, the subsidence between the larger settlement and the subsidence will occur. In local depression, the foundation loses support and produces relative displacement. The upper load can only be borne by the brickwork, then additional tensile and shear forces are generated on the brickwork. When the stress is greater than the carrying capacity of the brickwork, cracks will appear, most of the cracks appear in the lower part of the house, Development to the second and third floor. Therefore, this article mainly analyzes and discusses the problem of masonry cracks caused by uneven foundation settlement.
