Prestressed technology give ful play to the chara-cteristics of compressive strength of concrete and steel tensile strength, so it can reduce the weight, improve the bridge co-ncrete crack resistance and stiffness, and increase durability and cost. This paper mainly discusses the principle and const-ruction technology of prestressed technology, and put forward the common quality problems in the prestressed construction process and the solving measures.
