摘　　要：介绍了优势面理论的基本观点,通过区域优势断裂和场区优势断裂这两类优势面的分析,归纳总结了优势断裂等级划分的四个基本优势指标;结合活动性断裂研究方法,介绍了润扬长江公路大桥区域稳定性评价的工程实例.The preferred plane theory is a new model to assess regional stability for large bridge project.Based on the study of regional preferred fault and site preferred fault,four basic preferred indices to the classification of preferred fault degree are cleared.Combined with the method of active fault research,the main preferred faults to control stability for Run-Yang highway bridge Project are evaluated.

关 键 词：优势面理论 大型桥梁 区域稳定性 优势断裂
