Triaxial method Lab Report Example | Topics and Well Written Essays - 250 words
Triaxial method - Lab Report Example Insitu soil material is tested in during subsurface phase. This phase is an investigation stage that will help prepare design a waste containment facility or structures. The tests done will be used for structural fill, recompacted soil layers, and any other engineering components. These forms of tests are called conformance tests and are performed before any construction starts. Appropriate ASTM test methods must be followed when performing tests of materials. The common tests applied in geotechnical investigation are; Standard Test Method for Direct Shear Test of Soils Under Consolidated Drained Conditions ASTM 3080, Standard Test Method for Unconsolidated-Undrained Triaxial Compression Test on Cohesive Soils ASTM 2850, Standard Test Method for Unconfined Compressive Strength of Cohesive Soil ASTM 2166, Standard Test Method for Consolidated-Undrained Triaxial Compression Test for Cohesive Soils ASTM 4767 and Standard Test Method for One-Dimensional Consolidation Properties of Soils ASTM D 2435.1.0Ã Theoretical BackgroundThe purpose of this test is to establish the undrained shear strength of soil and applied to scenarios where fine-grained soils will be saturated and loading expected at a rate that overwhelms the ability of soil materials to dissipate excess pore water pressure. The author states that the shear strength parameters of fine and course grained soils in undisturbed or remolded state is quickly established. In a situation where the rate of construction is slow and allows the soil.
