This tool performs soil liquefaction assessment using SPT-based methods, implementing procedures consistent with established geotechnical practice.

Key Features

• Layer-wise liquefaction evaluation
• SPT normalization and fines correction (α–β method)
• CSR–CRR based factor of safety calculation
• Groundwater and seismic input control

Methodology

Based on procedures by Idriss & Boulanger (2008). The procedure includes magnitude scaling and stress reduction factors.
