Which consequence results when a dense concentration of defenders exceeds the design limits of piled earth siege ramparts during an attack?

💡 Explanation

Accelerated ramp subsidence occurs because the soil's bearing capacity is exceeded. This causes plastic deformation via the Terzaghi Bearing Capacity mechanism, therefore the ramp sinks. Rather than increasing stability , the added mass reduces the factor of safety against shear failure.
