格状与层状岩体边坡稳定性分析的概率方法

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，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，并考虑在水压力及地震灾害条件下，计算相应破坏要 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。

PROBABILITY ANALYSIS METHOD FOR THE STABILITYOF GRID AND BEDDED ROCK SLOPE

Using the Monte Carlo method,the normal slope model of grid and bedded rocks can be analyzed. With the random combination of steep and flat series of joints in the J-slope,the failure probability and reliability index can be calculated under the action of water and earthquake. The high slope stability of one copper mine in Jiangxi is analysed by the proposed method,and the result is satisfying.
