[提要]  对比《建筑基坑支护技术规程》(JGJ120-99)和《建筑基坑工程技术规范》(YB9258-97)中有关铺杆的设计规定，探讨了土层锚杆设计中的安全系数和试验荷载问题。结合《土层锚杆设计与施工规程》( CECS22:90)提出了采用建设部规程JGJ120-99设计永久性土层锚杆时的安全系数和试验荷载取值。

The safety factor and test load problems of soil anchors are discussed based on the comparison between two codes which are Technical Specification for Retaining and Protection of Building Foundation Excavations (JGJ120-99) and Code for Technique of Building Foundation Pit Engineering(YB9258-97). According to the Code for Design and Construction of Soil Anchors ( CECS22:90), appropriate safety factor and test load are recommended for the design of permanent soil anchors when using the technical specification issued by the Construction Ministry.
Keywords: soil anchor; safety factor; test load
