Is Code for Triaxial Test?

IS 2720(Part 12):1981 Determination of Shear Strength parameters of Soil from consolidated undrained triaxial compression test with measurement of pore water pressure

pore water pressure
Pore water pressure (sometimes abbreviated to pwp) refers to the pressure of groundwater held within a soil or rock, in gaps between particles (pores). Pore water pressures below the phreatic level of the groundwater are measured with piezometers.

(first revision). Reaffirmed- Dec 2016. 4.1 Triaxial Test on Cohesive Soil: 4.1.

Is code for direct shear test?

The procedure is same as in 4.1 except that after the application of normal stress, the vertical compression of the soil with time should be recorded [ scc IS : 2720 ( Part 15 )-1986* 1. The shear test should be conducted only after complete consolidation has occurred under the particular normal stress.

What is CU triaxial test?

Consolidated Undrained (CU) Triaxial Test

To find the shear strength parameters (c', Φ') of soil for effective stress analysis. CU triaxial test is recommended for all types of soil including cohesive and cohesionless soils.
