砌体开裂到处可见,乍看起来似乎都差不多,但仔细剖析一下,不同原因导致的砌体裂缝各不相同。这些不同点反映在裂缝的特征、位置、宽度、走向变化等方面,有其内在的规律性。掌握其规律,对确定砌体裂缝危险程度及如何修复是大有帮助的。一、强度裂缝砌体负荷达承载能力的80％时,即产生明显的强度裂缝。裂缝与荷载的大小、方向均有关系。显著的特点是裂缝的走向与荷载的方向、位置的对应性:若荷载是垂直向下作
Masonry cracks can be seen everywhere. At first glance, they all seem to be similar, but careful analysis reveals that cracks in masonry vary from one cause to another. These differences are reflected in the features, locations, widths, and trends of the cracks, and have their own inherent regularity. Grasping its laws is very helpful in determining the risk of cracks in masonry and how to repair them. 1. When the strength crack masonry load reaches 80% of the bearing capacity, it will produce obvious strength cracks. Cracks are related to the size and direction of the load. The salient feature is the correspondence between the direction of the crack and the direction and position of the load: if the load is vertically downward
