Shear box tests are generally suitable for cohensionless soil except fine sand and silt whereas triaxial test is suitable for all types of soils. Pressure changes and volume changes can be measured directly in triaxial test which is not possible in shear box test. Pore water pressure can be measured in the case of triaxial test which is not possible in direct shear test. Triaxial machine is more adaptable. The stress distribution across the soil sample in the failure plane is more uniform in triaxial test. The complete state of stress is known at all intermediate stages up to failure during the triaxial test whereas only the stress at failure are known in the direct shear test. In triaxial test, there is complete control over the drainage conditions, where control of drainage conditions is very difficult in shear box test.

What is Breslow-Gehan-Wilcoxon Test to compare kaplan curves?
This test evaluates differences between study groups, it allows weighting of time points by the number of cases at risk at each time point
What conditions are necessary in order to use a test to test the differences between two population means?
The samples must be randomly selected, independent, and normally distributed. The following are necessary to use a t-test for small independent samples. 1. The samples must be randomly selected. 2. The samples must be independent. 3. Each population must have a normal distribution.
Is there a statistical test to assess the difference between two ratios. I have numbers which are ratios and want to test whether there is a statistical difference between them?
You can use the z test for two proportions. The link below will do this test for you.
What is t Test?
t-test is the statistical test used to find the difference of mean between two groups
What are the difference between result obtained from ultrasonic test and triaxial test?
Triaxial testing will yield static strength properties of the material while ultrasonic measurements will give dynamic strength properties. The two can be related to each other by using various relationships between Young's Modulus, Bulk Modulus, Shear Modulus and Poisson's ratio. Static results should be lower than the dynamic results.
What is basic friction angle?
Friction angle or also known as angle of repose of soil is the subtended angle formed between the side slope with the vertical of a loose heap of the soil. This can also be determined by the triaxial shear test on soil conducted in laboratory.
Why vane shear test is done for clay only and not for sand?
Vane shear test is typically done for clay because clay is more likely to exhibit shearing behavior due to its cohesive nature, which requires a specific method to determine its strength properties. Sand, on the other hand, is generally considered non-cohesive and is better tested using other methods such as direct shear or triaxial tests to determine its strength properties.

How can one determine the shear modulus of a material?
The shear modulus of a material can be determined by conducting a shear test, where a force is applied parallel to the surface of the material to measure its resistance to deformation. The shear modulus is calculated by dividing the shear stress by the shear strain experienced by the material during the test.
Why modulus of rigidity is not considered in shear test?
The modulus of rigidity, or shear modulus, is not typically considered in shear tests because these tests primarily focus on determining the material's shear strength and behavior under shear loading. Shear tests, such as the torsion test or direct shear test, measure how materials deform and fail under shear stresses, rather than quantifying their elastic properties. While the shear modulus can be derived from the initial linear portion of the stress-strain curve in some tests, the main objective is to evaluate the material's performance and failure characteristics under shear conditions.

What is a soil test for build..?
There are a large number of soil tests related to construction:Particle Size Distribution test - finds the relative proportions of differing grain sizes within a soilAtterberg Limit test - used to establish the plasticity class of the soilCompaction test - used to find the optimum moisture content to achieve a maximum densityConsolidation / Oedometer testing - used to establish the settlement potential of a fine grained soil.Direct Shear test - used to measure the peak (and potentially residual) shear strengths of a soil. When tested at varying confining loads can be used to find the shear strength parameters Phi' and c'*Triaxial testing - used to find the elastic properties of the soil (Young's Modulus and Poisson's Ratio) along with the shear strength. These may be either drained or undrained tests.Constant and falling head permeability tests - used to establish the hydraulic conductivity / coefficient of permeability for coarse and fine grained soils respectively.*Note in the UK c' is assumed to be zero for design purposes, in other countries small non zero c' may be used.
