As a vast harbour, this port is the hub of the waterways from north to south of China, playing a key role in the transport of import and export goods for the provinces of northeastern China and the vast eastern part of Inner Mongolia.展开更多

Then reliability analysis method was used to generate the fragility curves of bridge components. And compared two kinds of bearing made differences to structure＇ s vulnerability. Researches show that bearing is easy to breakdown with earthquake action. Isolation bearing has good effect, and significantly reduces failure probability, fmaUy the fragility curves obtained can be used to evaluate the seismic performance of continuous beam bridge for port project, and provide the basis for seismic design of bridges for port project.展开更多
