近年来，随着我国交通事业的迅猛发展，高等级公路开始进入西部山区，大跨径预应力混凝土曲线刚构桥应运而生。本文以某大桥为研究背景，通过改变桥梁的曲率半径，分析了大跨径曲线连续刚构桥的预应力损失，可为连续刚构桥的施工提供一定的参考。
近年來，隨著我國交通事業的迅猛髮展，高等級公路開始進入西部山區，大跨徑預應力混凝土麯線剛構橋應運而生。本文以某大橋為研究揹景，通過改變橋樑的麯率半徑，分析瞭大跨徑麯線連續剛構橋的預應力損失，可為連續剛構橋的施工提供一定的參攷。
근년래，수착아국교통사업적신맹발전，고등급공로개시진입서부산구，대과경예응력혼응토곡선강구교응운이생。본문이모대교위연구배경，통과개변교량적곡솔반경，분석료대과경곡선련속강구교적예응력손실，가위련속강구교적시공제공일정적삼고。
In recent years, high-grade ways begin enter the South mountain areas under the backgroung of the rapid development of our counties' transport,so long-span prestressed concrete curve continuous rigid-frame bridges arise at the historic moment. Taking one bridge as the engineering background,by changing the radius of curvature,analysis the prestress loss of long-span curved continuous rigid-frame bridge, The study may provide some references for design and construction of curve continuous rigid frame bridge. The study may provide some references for design and construction of curve continuous rigid frame bridge.
