Answer for How do I design a pile foundation?

The pile foundations can be designed as the deep foundations. The piles, in general, can be designed as Friction Piles or Rock socketed or end-bearing piles. There are other several types of piles based on materials, type of construction, etc. However, the above two...

Answer for What is a mobilized shear strength?

When you apply a load on any structure, stress will develop. The stress would increase as you increase the applied load until it reaches the maximum possible value at which the material will fail. This self-adjusting phenomenon is called the mobilization of shear...

Answer for What is a Tunnel ? What are the types of Tunnel?

The tunnel is a horizontally excavated way of road/rail communication. It is constructed in a step-by-step procedure so that it does not collapse onto itself. As you know that soil is very weak in tension. So any excavation without proper structural reinforcement or...

Answer for What is negative skin friction? When does it happen?

Negative Skin friction is a type of skin friction that happens in a pile foundation. A deep foundation usually consists of piles (either bored or cast-in-situ). Each pile carries the load from super-structure by transferring the load through (1) Skin-friction and (2)...

Answer for What is a constitutive model of soil ?

A constitutive model of soil is the mathematical description of soil behavior in the elastic and plastic regime. It can be a strain rate dependent as well. A constitutive model is a fundamental notion for any higher-order numerical analysis like the Finite Element...
