邊坡穩(wěn)定性評(píng)估是地質(zhì)工程工程師研究的常規(guī)性課題。邊坡穩(wěn)定性預(yù)在大壩、道路、隧道、開(kāi)挖、露天礦等工程結(jié)構(gòu)設(shè)計(jì)起著重要作用。本文對(duì)巖質(zhì)邊坡穩(wěn)定性及滑坡的形成機(jī)理進(jìn)行了分析研究。水庫(kù)大壩建設(shè)是世界各國(guó)的重要研究課題,對(duì)于存在能源危機(jī)的發(fā)展中國(guó)家更是如此。水庫(kù)在蓄水過(guò)程中可能會(huì)激活古滑坡體、誘導(dǎo)或觸發(fā)滑坡。因此,本文對(duì)中國(guó)青海省浪加水庫(kù)左岸的1號(hào)滑坡A-A’剖面、2號(hào)滑坡剖面及3號(hào)滑坡剖面進(jìn)行了邊坡穩(wěn)定性分析。在邊坡穩(wěn)定分析中,安全值的主要指標(biāo)仍然是斜坡距離失效點(diǎn)初始值的大小。對(duì)于安全系數(shù)評(píng)價(jià)因子,基于極限平衡法的Bishop法和Morgenstern-Price法,對(duì)GeoStudio軟件的SLOPE/W模塊進(jìn)行剖面A-A’,剖面2和剖面3的二維邊坡穩(wěn)定性分析�；谟邢薏罘址ǖ膹�(qiáng)度折減技術(shù),將FLAC3D軟件用于邊坡3的邊坡穩(wěn)定性分析。在不同的工況條件下,使用上述兩種方法計(jì)算安全系數(shù)（FS）并繪制結(jié)果。分別運(yùn)用Bishop法和極限平衡Morgenstern-Price法對(duì)自然條件（a）、暴雨條件（b）地震條件（c）和水庫(kù)蓄水條件（d）這四種工況下的邊坡進(jìn)行了二維穩(wěn)定性計(jì)算。計(jì)算結(jié)果表現(xiàn)出:A...
