A method and an apparatus for measuring geogrid junction strength by a multi-junctional test are provided to easily select the most appropriate geogrid on a spot to be reinforced by compensating scale effect on a geogrid junction. An apparatus for measuring geogrid junction strength by a multi-junctional test includes a first clamp unit(10), a second clamp unit, and a tension unit(30). The first clamp unit includes a supporter(11) and a fixing unit(12). The supporter supports geogrid. The fixing unit has coupling holes for fixing one side of a geogrid rib. The second clamp unit includes a supporter supporting the geogrid and a fixing unit(22) having coupling holes(22a) for fixing the other side of the geogrid rib. The tension unit is installed on the first clamp unit, moves up and down for expanding geogrid, and measures geogrid multi-junctional strength.
