摘要
斜塔斜拉桥是一种新型桥梁结构形式,该桥型结构特殊且受力复杂,主要是通过塔的倾斜来平衡桥面恒载和活载。通过一般斜拉桥的分析理论来分析斜塔斜拉桥,其关键是考虑主塔的倾斜,进一步通过对斜塔的受力分析,得出斜塔斜拉桥的力学分析方法。
The cable stayed bridge with diagonal tower is a new type of bridge structure. Present structure is particular and its load -bearing is complex, so the dead and live loads of deck are balanced mainly by tower obliqueness. When analyzing the cable - stayed bridge with diagonal tower by general analytic theory, the key lies in taking the obliqueness of main tower into accout. In response to further analysis of load - bearing of diagonal tower, the mechanics analyzing methods for this type of bridge are obtained.
