（湖南大學(xué)土木工程學(xué)院 長沙 410082）[提要] 對(duì)比《建筑基坑支護(hù)技術(shù)規(guī)程》(JGJ120-99)和《建筑基坑工程技術(shù)規(guī)范》(YB9258-97)中有關(guān)鋪桿的設(shè)計(jì)規(guī)定，探討了土層錨桿設(shè)計(jì)中的安全系數(shù)和試驗(yàn)荷載問題。結(jié)合《土層錨桿設(shè)計(jì)與施工規(guī)程》( CECS22:90)提出了采用建設(shè)部規(guī)程JGJ120-99設(shè)計(jì)永久性土層錨桿時(shí)的安全系數(shù)和試驗(yàn)荷載取值。
[關(guān)鍵詞] 土層錨桿 安全系數(shù) 試驗(yàn)荷載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
