The paper provides the calculation formula for the anchor bolt steel damage and extraction of the anchor bolt according to GB 50010 Concrete Structural Design Regulation, but did not consider the concrete base materials damage in embedded parts, referring to the related regula-tions at home and abroad, compares and sums up the calculation methods for the embedded parts concrete damages, and simplifies the calculation according to the status in China and related components, so as to meet the accurate demands of most projects.%鉴于GB 50010混凝土结构设计规范中只给出了相应的锚栓钢材破坏和锚栓拔出破坏的计算公式，但未对预埋件的混凝土基材破坏进行考虑，参考了国内外相关规范，对预埋件混凝土破坏的计算方法进行了比较总结，根据我国国情及相关构造简化了计算，满足大部分工程的精度要求。
