摘　　要：某仓储浅圆仓出现了结构差异沉降,经过现场调研及对浅圆仓的施工、使用情况及沉降观测数据的整理分析,找出了A1仓结构基础出现较大差异沉降的原因,并结合工程实际提出有效阻止其继续发展的技术方案。证明了注浆加固和锚杆静压桩加固这两个方案在本工程中的可行性,并分析了二者优缺点。最终加固方案为锚杆静压桩加固浅圆仓基础、压密注浆处理浅圆仓基础外侧地基。A squat silo experienced structural differential settlement.After on-site research and analysis of the construction,usage,and settlement observation data of the squat silo,the cause of significant differential settlement in the foundation of the A1 squat silo is found.And propose effective technical solutions to prevent its continued development based on engineering practice.Proved the feasibility of grouting reinforcement foundation and anchor static pressure pile reinforcement foundation in this project,and analyzed the advantages and disadvantages of both.The final reinforcement plan is to reinforce the shallow circular warehouse foundation with anchor static pressure piles and to treat the outer foundation of the shallow circular warehouse foundation with grouting reinforcement.
