摘　　要：本文结合结构可靠性评估特点,应用未确知测度、置信度的概念,建立了基于未确知测度的工程结构可靠性评估模型,并结合工程实例,验证该模型在处理大量不确定性影响因素时丢失信息少,得到的评估结果能够客观全面地反映结构可靠性。该评价方法操作相对简单,满足工程需要,更加实用。For the features of structural reliability assessment, the unascertained measure model and the in- credible degree were applied to establish a model of evaluating of structure reliability based on unaseer- rained measuring. Practical project was used to verify the efficient of the model by dealing with many un- certainty factors with less loss of information, and the assessment results received can be objectively and comprehensively reflect the structural reliability. The evaluation method was relatively simple to meet project needs and was practically.
