摘　　要：为了提高油脂原料仓液压滑模施工精度,以花生、大豆优质粮油生产项目为背景对筒仓液压滑模施工精度影响因素进行识别,运用ISM-MICMAC理论的方法建立影响因素多层递接模型,并以层次分析法(AHP)计算各影响因素的权重比。结果表明:操作平台没有足够的强度和适当的刚度、支承杆弯曲失稳及滑模装置组装不规范是造成滑模施工过程中精度控制不佳的最直观表现形式;液压千斤顶顶升不同步和外界温度过高或过低是影响施工精度的最重要因素。该分析方法明确了影响因素之间的作用关系,找出了影响施工精度的最重要因素,为原料筒仓壁施工的顺利完成提供了一定的参考。In order to improve the construction accuracy of hydraulic sliding form for oil raw material silos,the factors affecting the construction accuracy of hydraulic slip form for silo were identified based on the peanut and soybean high-quality grain and oil production project.Using the method of ISM-MICMAC theory,the multi-layer recursive model of influencing factors was established,and the weight ratio of each influencing factor was calculated by analytic hierarchy process(AHP).The results showed that the lack of sufficient strength and proper stiffness of the operating platform,the bending instability of the support rod and the irregular assembly of the sliding form device were the most intuitive manifestations of poor precision control during the sliding form construction process.The asynchronous lifting of hydraulic jacks and the high or low external temperature were the most important factors affecting the construction accuracy.The method clarifies the relationship between the influencing factors,finds out the most important factors affecting the construction accuracy,and provides a certain reference for the smooth completion of the construction of the raw material silo wall.
