Explore lateral earth pressure, including active, passive, and earth pressure at rest on retaining walls, and how the coefficient of earth pressure relates to horizontal and vertical stresses.
Explore earth pressure at rest on a retaining wall; derive k0 as sigma_h'/sigma_v' with zero net force, and mu/(1-mu) where mu is Poisson's ratio, noting sandy and OC clay formulas.
Learn the differences between active and passive lateral earth pressure, including major and minor principal stresses, failure wedges, and the theta angle, with a preview of Rankine's earth pressure theory.
Explore Rankine's earth pressure theory, its homogeneous isotropic cohesionless soil assumptions, plane backfill, smooth vertical wall, and active–passive states with ka and kp relations.
Apply Rankine earth pressure theory to dry soil, derive horizontal stress as k a times vertical stress, and compute the pressure diagram and F = 1/2 k a gamma h^2.
Explore earth pressure variation in stratified soil with two cohesionless layers, derive horizontal stresses using ka and sigma_v', analyze the interface, and use Carignan theorem to locate the resultant force.
Explains how cohesive soil behavior alters earth pressure, introduces tension cracks, and derives horizontal stress relationships for C5 soil beyond Rankine's cohesionless assumption.
Examine how tension cracks affect earth pressure in active soil and the passive C5 case. Show how cracks make upper soil a separate body and alter net earth pressure calculations.
This course is taught by Mr. Vishal Bhatt who did his engineering from Indian Institute of Technology (IIT Roorkee) that was established in 1847 and the oldest and most prestigious institute for Civil Engineering in Asia. He has been into teaching field from last 10 years and have guided more than 30,000 in offline institutes across the country. He taught students from various countries in the past 4 years of span of online teaching and have grown a community of about 50,000 students on youtube.
This course on basics of earth pressure will make you understand why earth pressure acts and what are the different states of soil depending upon earth pressure and how you can determine the value of earth pressure force that will be helpful in designing any retaining structure.
This course is completely taught in English language along with some numerical examples to boost your confidence not only in academics but also in the practical field.
In this course you are going to study about Rankine's earth pressure theory for cohesionless soil and also its application to cohesive soil.
This course is beneficial to all civil engineers because every structure or construction is done on the earth surface and definitely we should understand the impact of lateral earth pressure before designing any structure as a civil engineer.
