摘要
在预应力混凝土曲线箱梁桥中,预应力钢束产生的径向分布力是混凝土曲线箱梁产生扭矩的主要原因之一。因此,工程师们必须认识到扭矩分析的重要性,并掌握预应力钢束对混凝土曲线箱梁产生扭矩的原理及计算方法,建造出安全、经济、美观的曲线梁桥。
In prestressed concrete curved box girder bridge construction, the plane-curved tendon wall yield great radial horizontal pressure, which is one of the main reason that will bring the destroy of the curved box girder bridge. It is very important for the engineer to master the principle and the calculation method that plane-curved tendon brings with, and construct the safety, economic, beautiful curved box girder bridge.
