随着大跨度的需求越来越大，普通混凝土已经不能满足要求，预应力混凝土应运而生。预应力混凝土构件抗裂度及刚度大大提高、耐久性增加、节约混凝土、自重较轻等优点，让大跨度跨江大桥，高强度、超高层建筑成为可能。本文主要阐述预应力混凝土在工民建中的广泛应用。

Along with the demand of large span is more and more big, the ordinary concrete has been unable to meet the requirements prestressed concrete emerged as the times require. Advantages of prestressed concrete structure crack and stif ne-ss greatly increased, increased durability, concrete saving, ligh-ter weight, let the big span bridge across the river, high streng-th and super high-rise buildings become possible. This paper mainly discusses applications of prestressed concrete in indus-trial and civil engineering.
