Which risk increased during Roman siege ramp construction?

💡 Explanation

Increased compression risk arose where underground aquifers existed, because the added weight and compaction from the ramp caused increased soil pore pressure affecting hydraulic head, therefore tunnel collapses increased rather than other failure modes due to the soil properties.
