本工程为超长结构,总长度约360m,宽约100～120m,设计中通过技术措施解决此问题;由于建筑要求,地上中间部位设计了大空间和自动扶梯(大开洞),柱网不规则,形成长悬挑(4.5～6m)和大跨度(18～20m左右),考虑到层高和各专业设计配合的要求,梁高不得不控制在1m以内,因此该区域的钢筋混凝土梁加设预应力钢筋,得以实现建筑的构想。
The project is a long structure with a total length of 360m and a width of 100-120m. This problem is solved through technical measures in the design. Due to the construction requirements, large spaces and escalators (large openings) are designed in the middle of the ground. Rules, the formation of long overhang (4.5 ~ 6m) and large span (18 ~ 20m or so), taking into account the requirements of the stratum height and the professional design and coordination, beam height has to be controlled within 1m, so the region of reinforced concrete beam plus Prestressed reinforcement, to achieve the idea of building.
