Reasons for the high cost of Jinmen Bridge
The bridge has a long span and a large amount of work;
The water depth engineering of steep channel on both sides of the strait is difficult;
Poor construction conditions in rainy and foggy weather;
Located at the junction of the Pacific plate and the American plate, the crustal movement is active and the technical level is high;
Seawater is corrosive, which requires high building materials for bridges.
Expansion: The bridge cost can be analyzed from the aspects of topography, climate, hydrology, geology and technology, and these factors * * * determine the bridge span, construction conditions and materials.
According to the information and knowledge learned, the Golden Gate Bridge is 2780 meters long, with a long bridge body, a large span and a large amount of work. Topographically, the two sides of the Taiwan Province Strait are steep, and the navigation channel is deep, which makes the project difficult. Climate: rainy and foggy weather, heavy wind and waves and poor construction conditions; Hydrology, cross-sea bridge, seawater is corrosive, which requires high bridge materials; At the same time, the area is located at the junction of plates, with active crustal movement, complex geological conditions and high technical level of bridge construction; The above factors are the reasons for the high cost of the Golden Gate Bridge.
