Scope

Scope: This document specifies the test method for single-hole shear wave velocity; Main technical content: This document specifies the test method for single-hole shear wave velocity. The test method described in this document is suitable for single-hole shear wave velocity testing within a depth of 50 m. It requires that the borehole be a straight borehole, i.e., with an inclination angle of 90°. Boreholes with an inclination angle deviation of within 3° can be approximated as straight boreholes and tested according to the method described in this document.
