Understanding Dynamic Loads and Engineering

What happens here

The speaker explains the critical design considerations for this specific retaining wall project. Due to the presence of large trees immediately behind the wall, a 'dynamic load' is created as the tree roots expand over time, pushing against the wall. This is contrasted with a 'static load' from elements like a garage or asphalt, which exert constant, non-changing pressure. To account for this dynamic load and prevent failure, the wall requires specific engineering and the extensive use of geogrid as reinforcement behind the blocks. The discussion highlights the need for careful planning and adherence to engineered specifications.

Goal: Explain the engineering challenges and solutions for the retaining wall, especially concerning dynamic loads.
