【摘要】 阐述了高边坡发育的地质环境,描述了高边坡变形的主要特征,这些特征主要表现为边坡上部的蠕滑拉裂及中部的倾倒变形等,根据这些特征,分析了高边坡变形破坏的潜在模式,并对潜在滑面的参数进行了试验分析及取值研究,最后结合高边坡可能遇到的各种工况条件对其稳定性进行了估算,结果表明,该边坡在天然条件及降雨条件下处于稳定状态,地震条件下处于极限平衡状态,而在泄流雨雾及降雨叠加地震条件下均将失稳破坏。更多还原

【Abstract】 The geological conditions and main deformation characteristics of high slope are described,those characteristics mainly include creeping-crack in upper portion and the toppling deformation in middle portion of the high slope.Based on these considerations the potential failure model of the high slope is analyzed and the tests of the parameters of underlying sliding plane are carried out.The stability of the high slope is estimated and calculated according to the various natural condition possibly occurred.The results indicate that the slope will be in stable condition under natural and rainfall,in limiting equilibrium condition under earthquake,and will be in unstable state under the effect of the discharging atomization or combined the rain and earthquake.更多还原
