| Resumen: | This part of BS 1377 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 BS 1377. 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 BS 1377 for general requirements that are relevant to all Parts of this standard, and to Parts 1 and 4 for methods of preparation of soil and of test specimens. Direct shear tests (clauses 3 to 6) comprise:
Compression tests (clauses 7 to 9) comprise:
The unconfined compression test procedure using portable apparatus, and the single-stage triaxial compression test, are similar in principle to those given in the 1975 Standard. All the other procedures are new additions.
