| 摘 要： | 大跨度无粘结预应力板施工中，经过计算，将整板受力支撑改为三跨受力支撑，避免了预应力张拉时，因混凝土强度需达到100％设计强度等级标准值的条件限制，造成大量模板、钢管等周转材料的积压，降低了成本，提高了经济效益。

| Abstract: | In the construction of large-spanned non-bonding pre-stressed slab, instead of all-slab support, three-span support is adopted after calculation, which can avoid serious overstock of formwork and steel pipe caused by the restriction that concrete must reach 100% design strength when applied pre-stress. Cost is therefore reduced and economical benefit improved. |

| Keywords: | large span non-bonding pre-stressed slab local support |
