厚板基础是高层建筑常用的基础形式。厚板一般指厚跨比为1/5～1/8。厚板基础整体性好,刚度大,能有效地分散上部结构的荷载,调整基底的压力和不均匀沉降,并且有较好的抗渗性能。厚板基础板较厚,便于布筋,施工方便,能为建筑提供开阔的地下空间。厚板基础设计中,除需要满足强度要求外,还要考虑差异沉降和裂缝等多种因素。如何确定板的内力和配筋,如何确
The slab foundation is a common basic form of high-rise buildings. Thick plates generally have a thickness-to-span ratio of 1/5 to 1/8. The slab foundation has good integrity and rigidity, can effectively disperse the load of the superstructure, adjust the pressure and uneven settlement of the substrate, and has good impermeability. Thick plate base plate is thicker, it is convenient for ribbing, construction is convenient, and it can provide open underground space for the building. In addition to the strength requirements, a variety of factors such as differential settlement and cracks must be considered in the design of slab foundations. How to determine the internal force and reinforcement of the plate
