摘　　要：根据调查和分析在役码头现状,提出维修方案。为提高施工期间对混凝土码头的影响,采用相关软件对混凝土码头的受力情况进行了验证分析,主要考虑排架承载能力极限状态桩受力、正常使用极限状态桩受力、单桩抗压极限承载力、横梁正截面强度和横梁斜截面强度等指标进行了系统分析,结果表明施工期间码头的排架受力稳定满足安全要求。还对施工期间的施工安全、环境保护等方面提出了具体措施。Based on the investigation and analysis of the current status of the in-service wharf,a maintenance plan is proposed.In order to improve the impact on the concrete wharf during the construction period,the relevant software was used to verify and analyze the stress condition of the concrete wharf.The main consideration is the limit state pile force of the bent bearing capacity,the normal service limit state pile force,and the single pile compressive limit.The load-bearing capacity,the strength of the cross-beam normal section and the strength of the oblique section of the cross-beam were systematically analyzed,and the results showed that the stable force of the bent frame of the wharf during the construction period met the safety requirements.It also proposed specific measures for construction safety and environmental protection during the construction period.
