Jennings边坡 (简称J边坡 )是一种常见于格状与层状岩体中的典型岩质边坡模型 ,论文在岩质边坡中对J边坡运用蒙特卡罗方法进行概率分析 ,考虑陡、缓倾角两组节理随机组合 ,对计算范围内节理分布进行位置搜索 ,并考虑水压力及地震灾害条件下 ,计算相应坡坏概率及其可靠度指标。使用该方法对江西某铜矿高边坡工程进行了计算 ,取得令人满意的结果
The Jennings slope (J slope) is a typical rock slope model commonly found in trellis and stratigraphic rock mass. The thesis analyzes the probability of J slope using Monte Carlo method in rock slope, Considering the random combinations of the two groups of steep and gentle dip angles, the position search of the joint distribution in the calculation range is performed. Under the condition of water pressure and earthquake disaster, the corresponding probability of slope failure and its reliability index are calculated. Using this method, a high-slope project of a copper mine in Jiangxi Province was calculated and satisfactory results were obtained
