| 摘 要： | 文章应用动力弹塑性分析方法对土工格栅加筋坝坡的抗震效果进行了研究；通过分析强震作用下坝体的地震反应特性,在加速度反应较大的坝坡——坝顶(1/5H)范围,对称铺设土工格栅；根据地震作用后坝体的剪应变、永久位移以及稳定安全系数来评价其抗震加固效果,同时研究了高土石坝加筋后的破坏机理.结果表明,土工格栅加筋能加强坝顶区堆石体...

| Abstract: | This paper studies the anti-seismic effects of geogrid reinforced dam slope by using dynamic elasto-plastic analysis method.By studying the dynamic responses of high earth-rock filled dam under strong earthquake,the geogrids are installed symmetrically in the dam slope(1/5H) with a stronger acceleration response.The dam body's shear strain,permanent displacement and safety factor of stability after earthquake are taken into account and used as a criterion to evaluate the anti-seismic effects.The failure mec... |
