Abstract

Model test is used to study the impact resistance of arch shaped shed tunnel, which mainly analyzes the dynamic response rules of arch, upright column and interior steel under diverse impact energy, cushion with diverse thickness, diverse impact locations; The rules of rockfall impact force and displacement of arch shaped shed tunnel under diverse impacting condition are analyzed; Failure mode and weak area of arch shaped shed tunnel are analyzed; The relative strengthening measures and appropriate thickness range of light soil cushion are given.

Key words

Arch shed shaped tunnel / Model test / Rockfall impact / Light soil / Dynamic response
