由于受地基变形等原因影响,使储油罐罐体的位置产生纵向倾斜和横向偏转等变化,从而导致罐容表读取数据和实际数据偏差很大.为了解决由于储油罐变位而导致的罐容表计量误差问题,采用了基于体积计算的微元法对两端平头圆柱体储油罐变位后的识别及变位后罐内油量进行重新标定,建立了相应的变位识别模型和储油罐在水平和倾斜放置时的罐容标定计算公式,并结合储油罐的变位特征,给出了模型适用范围的计算公式和模型的具体求解步骤,最后通过具体实例对模型进行了检验.检验结果验证了模型的正确性和可行性.%Due to influence of foundation deformation, the oil tank position can change longitudinal tilt and lateral deflection, lead to exist large deviation between the read data and actual data of storage oil. In order to solve the error problem .adopt the identifying technology of infinitesimal method based on the calculation of the volume and calibrating the tank volume after changing position,establish the corresponding calibration model and tank capacity calibration formula,give the model solution steps by the features of changing position. Finally, the model is tested through the examples,the test results have confirmed the correctness and the feasibility of the model.
