Soils for civil engineering purposes - Test method -
Part 7: Shear strength tests (Total stress)
This Malaysian Standard describes methods of test for determining shear strength parameters of soils in terms of total stresses, or (in the case of drained direct shear tests) in terms of effective stresses which are equal to total stresses. None of these procedures therefore requires measurement of pore water pressure, which is covered in Part 8 of MS 1056. Shear strength is determined either by measuring the shearing force causing failure (direct shear tests), or by derivation from the measured compressive strength (unconfined or triaxial compression tests).
Reference is made to Part 1 of MS 1056 for general requirements that are relevant to all Parts of this standard, and to Part s 1 and 4 of MS 1056 for methods of preparation of soil and of test specimens.
Direct shear tests comprise:
a) laboratory vane test procedure, for soft to firm cohesive soils;
b) small shearbox procedures for determining the angle of shear resistance of cohesionless soils, and the drained peak and residua
