摘要
通过改变桥台抗扭刚度和宽跨比,研究对斜交拱桥受力的影响。比较了1座单孔斜交拱桥和1座双跨斜交拱桥分别在自重荷载和车道荷载作用下的受力特性变化,得出增大桥台刚度能改善斜交拱桥在自重作用下的受力特性,但对单孔斜交拱桥的改善更明显;宽跨比变化对斜交拱桥的受力性能影响不大。
The influence to stress of skew arch bridge was studied by changing the abutment torsional stiffness and width-span ratio. The different stress characteristics of a single hole skew arch bridge and a double span type were compared in self-weight load and traffic lane load separately. It showed that increasing abutment stiffness could improve skew arch bridge stress characteristics under the self-weight load, especially for the single hole type and the changes of width-span ratio just had little influence on the stress performance.
