In past centuries, a lot of concrete Bridges were constructed in the word, and the bridge designer paid more attention to structural intensity, but ignored structural durability.
然而，在以往的设计中，由于片面的追求强度，因而忽视了桥梁耐久性，导致很多已建混凝土桥梁出现耐久性局部失效和老化现象。
Concrete cable-stayed bridge is a competitive structural system in the long-span bridge family in virtue of its good performance such as durability, low cost of construction and maintenance, etc.
混凝土斜拉桥以其耐久性好、造价和维护费用相对较低等优势已成为大跨桥梁结构中极具有竞争力的桥型。
