摘　　要：为解决传统钻前工程泥浆储备罐钢筋混凝土支墩存在的现场湿作业环境影响大、工程造价高、现场吊装难度大等问题,文章提出了装配式钢结构泥浆储备罐支架并对其进行结构设计。基于承载力对支架的承重形式进行深化设计,并建立精细化的全装配式钢结构支架有限元模型,对该支架的位移、弯矩、轴力进行有限元分析,确定支架的施工方案;同时在施工阶段选取支架关键节点进行应变监测,与软件模拟数据进行对比与验证,研究成果能为钻前工程装配建设提供重要的参考依据。In order to solve the problems existing in the reinforced concrete buttress of the traditional pre-drilling engineering mud reserve tank,such as large environment impact of on-site wet operation,high engineering cost,and difficult on-site lifting,the paper puts forward the prefabricated steel structure mud reserve cans support and carries out its structural design.Based on the bearing capacity,the load-bearing form of the bracket is deepened,and the refined finite element model of the fully assembled steel structure support is established to establish a finite element analysis of the displacement,bending moment,and axis of the bracket to determine the construction plan of the bracket;At the same time,the key nodes of the bracket are selected for strain monitoring during the construction phase,and the results are compared and verified with the software simulation data,and the research results can provide an important reference for the assembly and construction of pre-drilling engineering.
