自锚式悬索桥合理成桥索力探讨

Discussion on Rational Bridging Cable Force in Self-anchorage Suspension Bridges

基于三元构件之斜拉桥合理成桥状态确定的思想,给出刚性支承连续梁法和最小弯曲能量法确定自锚式悬索桥合理成桥索力的思路,讨论落架方式对成桥索力的影响,并以佛山平胜大桥为例,进行实桥分析计算。

Based upon the theory, of determining rational bridging status of cable stayed bridges of ternary components, this paper puts forward the idea of determining rational bridging cable force for self- anchorage suspension bridges by rigid support continuous beam method and rain. bending energy method. It discusses influence to bridging cable force by different supporting method, and gives practical analytic calculation to Fushan Pingsheng Bridge.
