连续刚构桥具有线形优美，行车平顺等优点，目前已经是一种比较常见的桥型。随着设计跨度的增大，以及早先修建的连续刚构桥的老化，连续刚构桥的下挠问题日益严重。那么如何设置施工预拱度，才能使连续刚构桥在成桥时具有理想的线形，并在以后的长期使用阶段避免产生过大的下挠变形。本文通过实例分析了连续刚构桥预拱度的计算方法，希望能对同类型桥梁施工时底模立模标高的设置提供参考。

The Continuous rigid frame bridge have the advantage of beautiful line-type and etc,so it is a common bridge type.But,as the bridge span become larger and larger and the the previous bridge getting old,the question of down warping of bridge grider get worse.Sohow sho-uld we set the con-struction pre-camber to make the bridge have ideal line-type while itis bu-ilt and to avoid the heavy downwarping deformation.This text hasmade a study of theseproble-ms to make a general reference for the same kind of bridge construction.
