【Abstract】 In this paper,the working condition of the measuring segment of Model SZY01 vane in-situ shear instrument is analyzed,and the planar multi-object optimization mathematical model of the vane pole is set up,in which the optimized objects are the diameter and the length of the vane pole.With the help of the optimization module of the toolbox of MATALAB 6.5,the optimum diameter and the length of the vane pole is also obtained based on the limit condition.The contrastive insitu tests on experiment samples were carried out respectively using vane shear instrument with the optimized vane pole or the initial vane pole in indoor.Taking data measured by portable shearing instrument as the reference,the data obtained by the vane shear instruments are compared,and the result has been proved that the vane shear instrument with the optimized vane pole can improve the testing precision.更多还原
