砖拱结构在建筑中应用较广泛。但由于对其特点注意不够,发生了一些倒塌事故。因为这种结构倒塌常是整体倒塌,且发生在一瞬间,所以危害较大。经过对近两年倒塌事例的分析,为防止事故的发生,应注意以下几点:一、要保证拱脚支座处有足够的抗推能力。拱体在拱自重和荷载作用下,在支座处不仅产生垂直作用 Brick arch structure is widely used in buildings. However, due to insufficient attention to its characteristics, some collapses occurred. Because this collapse of the structure is often an overall collapse, and occurs in an instant, so the harm is greater. After analyzing the collapse cases in the past two years, in order to prevent accidents, attention should be paid to the following points: First, it is necessary to ensure that the arch foot support has enough anti-pushing capacity. The arch body not only produces vertical effect at the support under the weight of the arch and the load
