张拉弦钢拱架结构是一种新型的预应力钢结构体系。
The stressed-arch frame is a new type of prestressed steel structure system.
随着预应力在桥梁施工中的普遍应用，预应力张拉控制已成为桥梁上部结构施工中的一道重要工序。
With the common application of prestress in bridge construction, the strain-pull controlling has become an important working procedure during the upper structure construction of bridge.
该改造工程不需要对预应力钢筋二次张拉和对结构进行临时支撑，因而明显地缩短了施工周期并节省了工程费用。
Using this new technology, there needs no the second tensioning of the prestressing tendons and temporary braces, thus the construction period and cost can be cut down obviously.
