Development of the Borehole Direct Shear Testing Apparatus

Abstract

The physical parameters of soil is the foundation of engineering. If data is not the exact value of any geotechnical engineering, it will not get the exact design and evaluation. This paper introduces a borehole direct shear testing apparatus can accurately and quickly get soil shear strength at any depth. It overcome the in-situ shear strength test is not accurate enough, long test time defect, fully meet the requirements of the indicators of field testing.
