摘　　要：为了研究瀑布沟水电站高陡边坡拉裂变形体的稳定性,经过系统分析其工程地质条件,提出了该拉裂变形体的变形破坏模式,主要为槽状的滑塌变形、倾倒拉裂变形、滑移拉裂变形、滑移压致拉裂变形。并通过有限元PLAX IS数值模拟软件以及室内试验对拉裂变形体稳定性进行模拟分析。结果表明:目前该拉裂变形体存在的变形破坏为松动带的滑塌以及倾倒拉裂区的滑移拉裂破坏,为后续实际工程处理方案的确定提供了可靠的依据,并对类似工程有一定的借鉴作用。In order to study the stability for high and steep slope with the tension crack body in Pubugou hydroelectric power station,its failure modes were classified,such as collapse like groove,tension fracture with dumpage,tension fracture with slippage,tension fracture with slippage and press according to its engineering geology condition.And its stability was simulated and analyzed by numerical simulation software-PLAXIS and indoor testing.The results showed that its failure mode are collapse of loosening zone and slippage with tension fracture of dumpage zone and tension fracture at present,which offers the reliable reference for confirming the treatment schedule of subsequent engineering and a sample for analogous engineering.
