A direct boxsheartest on granular material is successfully simulated by means of distinct element method.
用离散单元法模拟了粒状体的直剪试验。

The developed laminar shear model box lays a firm foundation for the success of the test and can also be adopted in other tests for seismic geotechnical problems.
So a split-type shearbox is adopted to conduct the in-situ sheartest in order to make the stress on the shear plane uniform and ensure the shear stress to running through the center o.
