摘要
结合石岐河特大桥的工程概况与主要技术指标,选取了(70+120+70)m连续刚构主桥方案,并从上部构造、预应力束布置、下部结构等方面,阐述了主桥的设计要点,以确保桥梁的安全性。
Combining with the engineering general situation and main technical indicators of Shiqi River Bridge,this paper selected the（ 70 ＋120 ＋ 70） m continuous rigid frame main bridge scheme,and from the upper structure,pre-stressed beam layout,lower structure and other aspects,elaborated the design key points of main bridge,in order to ensure the safety of bridge.
