In a layered soil system, how does the presence of a weak layer affect the overall bearing capacity?

In a layered soil system, how does the presence of a weak layer affect the overall bearing capacity?

Step 1: Understand what a layered soil system is. It consists of different types of soil stacked on top of each other, each with its own strength.
Step 2: Identify what a weak layer is. A weak layer is a section of soil that is not as strong as the layers above or below it.
Step 3: Recognize that the bearing capacity is the ability of the soil to support loads without failing.
Step 4: Realize that when a weak layer is present, it can fail under lower loads compared to stronger layers.
Step 5: Conclude that because the weak layer can fail first, it reduces the overall bearing capacity of the entire soil system.
