十字板优化轴试验研究

文章设计了十字板剪切仪的静态标定方案，按深海底沉积物剪切强度力学特性分层配制试验样品，并在室内分别采用便携式剪力仪对样品进行手剪和十字板剪切仪采用优化杆和原杆对样品进行原位测量，试验结果说明试验室十字板剪切仪原位测量剪切强度值接近且均小于便携式剪力仪剪切强度测量值、采用优化杆原位剪切强度测量的精度优于采用原杆原位剪切强度测量精度。

The Test of the Optimazed Vane Pole of Vane Shear Instrument

The paper designed the way to demarcate precision of the in-situ test vane shear instruments. And three experiment samples were confected according to the shear strength of the seabed sediments. Also the first experiment sample was sheared by hand with the portable shearing instruments, the other experiment samples were seperately tested by the vane shear instruments with the optimazed vane pole and the unoptimazed vane pole under the indoor in-situ contrastive test. Ultimately, the results were obtained that the shear strength of the samples tested by the vane shear instruments were a little less than that of the portable shearing instruments and the precision of the test by the vane shear instruments with the optimazed vane pole was better than that of the vane shear instruments with the unoptimazed vane pole.
