Design of prestressed anti-floating anchor with enlarged head of PSB screw-thread steel bars
Based on a PSB screw-thread steel bars prestressed anti-floating anchor with enlarged head project in Chengdu,the design and calculation method of PSB screw-thread steel bars prestressed anti-floating anchor with enlarged head was introduced.According to the Technical standard for anti-floating construction engineering(JGJ 476-2019),Technical specification for high-pressure jet extended head anchor(JGJ/T 282-2012),Code for design of concrete structures(GB 50010-2010)(2015 edition)and other national standards for PSB screw-thread steel bars prestressed anti-floating anchor with enlarged head from the bearing capacity of PSB screw-thread steel bars prestressed anti-floating anchor with enlarged head,anchor material selection and strength calculation,prestress loss and prestressed tension calculation,anchor pier area compression section size check calculation,raft foundation anti-cutting check calculation were carried out.The results show that the design and calculation of PSB screw-thread steel bars prestressed anti-floating anchor with enlarged head can meet the requirements of various codes in the industry.
