独柱墩桥梁抗倾覆验算及抗倾覆加固处治措施

Anti-overturning Check Calculation of Single-pillar Pier Bridge and Treatment Measures Against Overturning Reinforcement

通过对独柱墩桥梁在极端荷载条件下存在的倾覆隐患进行分析,提出了对独柱墩桥梁进行抗倾覆验算的三项指标(桥台支座最小反力、非固结墩支座转角、固结中墩压弯强度)和验算满足要求。当三项指标不满足验算要求时,结合参与主管过的独柱墩桥梁加固工程相关工作经验,提出相应的独柱墩抗倾覆加固方式及施工过程中的质量管理要点。为独柱墩桥梁在日常养护管理、加固设计、加固施工管理等方面提供了案例、技术参考和管理经验。

By analyzing the hidden dangers of single-column piers under extreme load conditions,three indicators for the antioverturning check of single-pillar piers are proposed(the minimum reaction force and the unconsolidated pier of the abutment support)The corner of the seat and the bending strength of the middle pier in the consolidation)and the calculation meet the requirements.When the three indicators do not meet the verification requirements,the author combined with the relevant work experience of the single pillar pier reinforcement project,and proposed the corresponding anti-overturning reinforcement method of the single column pier and the quality management points during the construction process.Provided case,technical reference and management experience for the singlepillar bridge in daily maintenance management,reinforcement design,reinforcement construction management,etc.
