GI-Liq

GI-Liq offers nearly all liquefaction analyses in one place. Deterministic and probabilistic liquefaction triggering assessment, dynamic settlement, lateral displacement, and residual strength all can be estimated in this module. The module supports SPT, CPT, BPT, and Vs in-situ data for comprehensive analysis. 

Results are presented in tabular and graphical formats and can be exported to Excel. Our software also generates an overview report summarizing input parameters and results.
