【Abstract】 The design scheme of piers,connecting bolts and tooling for straight pipe section is briefly described.Through theoretical calculation and calculation before production,the specification and quantity of connecting bolts were presented.The stress of pier base was analyzed by ANSYS finite element software to estimate the absence of failure of whole set of piers.The qualified piers and tooling were produced by vacuum EPC process.The pier base stress type test and pier base were simulated by hydraulic press.Simulatition of on-site installation reveals that absence of deformation and cracking can be observed.In addition,the field pull-out force test and analysis data of connecting bolts meet the design requirements.Through theoretical and practical verification,pier product quality meets customer requirements.更多还原
