Which risk increases when constructing structural foundations on sloping alluvial deposits?

💡 Explanation

When sloping alluvial deposits are saturated and experience seismic shaking, soil liquefaction occurs because intergranular contact decreases significantly, causing the soil to behave like a fluid and lose bearing capacity. Therefore liquefaction risk increases, rather than sulfate attack, decreased conductivity, or corrosion rates, which require different environmental conditions or interactions with the structure.
