工业建筑地坪结构设计问题的探讨

Study on Design of Ground Structure of Industrial Buildings

对于工业建筑的钢筋混凝土地坪厚度、配筋规格、地基土的处理,目前基本上无标准的计算模式和理论,设计随意性很大。工程实例中地坪开裂、起鼓、下沉现象较为频繁,有的还很严重,甚至危及建筑物本身的安全。该文就地面活荷载在30kN/m2≤P≤100kN/m2范围内的工业建筑地坪结构设计提出几点解决问题的意见,供参考。

At present there is no standard calculation formula and theory for the reinforced concrete ground of industrial buildings in the aspects of ground thickness,reinforcement grading and base-earth treatment,resulting in the design at will. There are many ground crack, protuberance and settlement phenomena in the engineering practices; some of them are very serious, even endangers the safety of the building above.The paper brings out the solutions to these problems in the ground structure design of industrial buildings when the load on ground ranges from 30kN/m^2 to 100kN/m^2.
