Cable

With the acceleration of the development of the national economy, the bridge is one of the important transportation hub of the country. At present, our country has built a large number of new structure, technology is complex, design and construction of a large degree of difficulty of the cable-stayed bridge, suspension bridge. Cable bridge is generally longer life span of 20 years, some of them to no more than ten years, this involves cable and suspender cable life expectancy. Through the detection of the cable force to determine the cable damage, broken wire method, the reasonable measure service life of the bridge itself, which is a difficult task of future safe operation of the transport hub worthy of attention.
