Which risk increases when improperly compacting soil around a buried, reinforced concrete column?

💡 Explanation

Decreased resistance to buckling increases because inadequate compaction results in insufficient lateral support. The column experiences increased effective length; therefore buckling resistance lowers dramatically rather than alternatives such as increased hydrostatic pressure, which compaction does not mitigate.
