Abstract The deformations and stresses of backfill of retaining wall are analyzed by elastoplastic numerical calculation model. The boundaries between backfill and retaining wall，and backfill and floor are simulated by interface elements that reflect interaction of them. The working mechanism of L-type retaining wall in permafrost region are studied and examined in detail，for providing reference for future engineering application.

Key words： Key words geotechnics frozen soil L-type retaining wall earth pressure frost-heaving force
