Description

This 3-hour course presents a step-by-step solution to a comprehensive range of 1-d consolidation problems for civil engineering students and professionals.

It covers the gap that exists in mainstream curricula that lack sufficient coverage of solved examples due to time limitations.

I have carefully selected the course problems so that they match those that you may come across in your assignments or exams. The course is also applicable to real-life settlement problems in clayey soils.

Who this course is for:
  • Civil Engineering Students
  • Civil Engineers and professionals
