Yunyang Yangtze River Bridge
云阳长江大桥
Yunyang, Chongqing, China
341 feet high / 104 meters high
1,043 foot span / 318 meter span
2005


Yunyang is a rare cable stayed bridge with asymmetrical towers. The taller tower is 85 feet (26 meters) higher above the Yangtze River. The design was necessitated by a steep river bank on one side that would have required constructing a very tall tower with its foundation deep under the Yangtze River. Instead, a shorter tower was built closer to the shoreline where the foundation could be built at the edge of the old Yangtze River level. Like many other big bridges that are over the 3 Gorges reservoir, Yunyang's height of 341 feet (104 meters) is now only half visible with the water level having been raised 246 feet (75 meters) over the old level of the Yangtze River. Yunyang means "clouded sun" which is probably a good description of the weather when I visited the city.


云扬长江大桥是一个座罕见的两座主塔不对称的斜拉桥。高塔在长江水面之上26米。这种结构设计的必要性,是归结于长江一岸很陡的河床,要求一个很高的主塔以及水面之下很深的基础。相反,相对较矮的主塔则可以把基础建在原油和到的边缘上。和三峡库区很多大桥一样,在水面上升了75米高之后,云扬长江大桥的距离水面的高度现在有104米,仅仅是原有河面之上的高度的一半,云阳的意思是“被云彩遮住的太阳”,恰好是当时我拜访该城市是的气候的最好的映照。
