摘　　要：山区高等级公路采用了许多非规则高墩桥梁,以跨越河谷和深沟,汶川地震的桥梁震害启示给山区高墩桥梁的抗震设计提出了新的要求。结合山区高墩桥梁的特点,阐述了山区高墩桥梁的概念设计、抗震计算和抗震措施三个方面的内容,为山区高墩桥梁抗震设计提供有益的参考。Because of complex topography of bridge sit,many high pier bridges with unconventional configurations in the western mountainous region are used in highway.The damages of the bridges in the Wenchuan Earthquake told us that the new concepts and measures should be used in mountain bridges design.With characteristics of high pier bridges in the mountainous region,the conceptual design,seismic calculation and seismic measurements of high pier bridges in the mountainous region are explained.It gives the benefit reference for the seismic design of high pier bridges in the mountainous region.
