Warnings
The warnings Rischio can raise on a pile or a pile group: what each one means and its level, for information or caution.
- Critical depth applied (for information). The pile is longer than and crosses at least one drained stratum: below , the effective stress along the shaft was held at its value at .
- Block failure governs (caution). : the group as a block carries less than its piles on their own, so the block sets . A wider spacing enlarges the block.
- Toe near another stratum (caution). The toe is closer than to another stratum, above or below it: the toe resistance is computed with its own stratum alone, and the other one may change it (Meyerhof).
- Unusual friction angle (caution). A stratum has above 45°: possible in rock fill, rare in soil, often a typing error. The calculation still runs, and at the toe stays at its 45° value.
