The prestressed reinforced concrete continuous rigid frame bridge is a kind of bridge which is nice wholeness , bearing property and has bright and pithiness bridge style .

预应力混凝土连续刚构桥是一种结构整体性好，受力合理，造型简洁明快的混凝土桥型，既保持了连续梁无伸缩缝，行车平顺的特点，又有T型刚构桥不设支座，施工方便的特点。

This kind of structure is fit for the comfortable steer with no other expansion joints except for those at the two ends. It characterized the wholeness of structure , good astigmatic ability and load-bearing ability , construction rapidness, bright and pithiness bridge style, so rigid frame bridge have taken an increasingly great proportion in bridges constructed and those under construction at city and county.

连续刚构桥能满足特大跨径桥梁的受力要求，除梁端以外无其他伸缩缝，有利于行车平顺舒适，具有结构整体性能好、抗震能力强、承载能力强，施工快捷等结构特点，因此在城乡已建和在建的桥梁中占据了越来越大的比重。
