Machine for the analysis of the resistance of soil, or of an anchorage structure, to the deflection of a post for a motorway guardrail

摘要

A description is given of a machine for the analysis, in situ, of the resistance of the soil, or of a restraining structure, to the deflexion of a post of a motorway guardrail, comprising a support frame (10). The support frame carries an analysis device (20) comprising a pair of guides (21), a slide (22) provided with means (24) for detecting the resisting force opposed by the post and sliding along the guides (21) between a rest or backward position and a work or advanced position, first means (25) for driving the slide (22), suitable for slowly driving the slide between the backward position and the advanced position, thereby performing a quasi-static resistance analysis, and second means (26) for driving the slide (22), suitable for rapidly driving the slide from the backward position to the advanced position, thereby performing a dynamic resistance analysis.
