Stability Study of the Geogrids Reinforced Tailings
In order to research the geogrid technology to improve the tailings dam stability,the paper introduces the mechanism of the geogrid reinforcing tailings dam and the simulation principle of the geogrids unit.It also introduces a calculation example.It uses the FLAC3D software to make a comparative study for the dam stability when geogrids reinforcing dam or no reinforcement. The result shows that: The X displacement value is reduced after reinforcement,but far from reinforced area X displacement is not change.It shows that the reinforcement effection appears at the reinforcement surrounding area.There is a little change about the landslide face after reinforced，which is more closer near early dam from the beach top. The safety coefficient rise from 1.69 to 2.37.The reinforcement effection is in good working order. The paper can provide some reference and instruction to the tailings dam safety.
