根据我国公路规范要求桥涵应根据所处环境条件进行耐久性设计。但目前我国桥梁设计相关规范仅按累年最冷月平均气温进行分区，为更利于指导处于多种环境条件下的桥梁的设计养护工作开展，本文通过对辽宁气象资料与实际情况结合分析，考虑年冻融循环次数与降水量等因素，尝试对辽宁寒冷濒海盐冻腐蚀环境进行合理分区，从而对不同区域采用有针对性的防治养护技术，提高综合效益，并为类似工程提供借鉴作用。

According to Chinese Highway Specification, bridge should be based on the environmental conditions for the durability design. But at present, environmental zones have been parted by the coldest month average temperature in design specifications of partition. The article carries out the design and maintenance work more beneficially, trying to part reasonable zone in Liaoning cold coastal salt freezing corrosion environment, which is based on analysis of meteorological data and with the combination of the actual situation, and considering year freeze-thaw cycles and precipitation etc. Maintenance works are done in different regions, comprehensive benefit is improved, and a reference for the similar engineering is pro-vided.
