近年来,由于沿海地区工业建设的迅速发展,在沿海软土地区受大面积地面堆载作用下的厂房建筑日益增多。而地面堆载对结构物作用的影响计算,目前还没有一个较完整和统一的方法。有些老企业的个别厂房,因受库房内大面积地面堆载作用的影响,使柱子和基础内倾,引起大小柱变截面处应力集中,致使裂缝超过了容许限值。其主要原因是地基不均匀沉陷严重和钢筋混凝土柱子在
In recent years, due to the rapid development of industrial construction in the coastal areas, plant buildings under the influence of large-area ground loading have been increasing in coastal soft soil areas. However, there is no more complete and unified method for the calculation of the impact of ground loading on the structure. Some of the old factory’s individual workshops, due to the impact of a large area of ground loading in the warehouse, caused the columns and foundations to tilt inwards, causing stress concentrations at the cross sections of large and small columns, resulting in cracks exceeding the allowable limit. The main reason for this is the uneven subsidence of the foundation and the reinforced concrete pillars
