裂隙岩质边坡广泛发育结构面,每条裂隙都对边坡稳定性具有影响并且相互之间组合会导致楔形体破坏。因此论文提出了基于随机动力学理论进行安全坡角估值的方法。该方法比传统的赤平投影方法更加合理。论文利用贝叶斯概率统计理论,把基于概率密度函数拟合曲线的均值参数进行优化后的期望值作为安全坡角的估值。以福建沿海地区某发电项目裂隙岩质边坡为例,采用本方法进行了边坡安全坡角优化。
Fractured Rock Slope Extensively developed structural planes, each of which has an impact on the stability of the slope and the combination with each other can lead to wedge destruction. Therefore, the paper presents a method of safety slope angle estimation based on stochastic dynamics theory. This method is more reasonable than the traditional stereoprojection method. In this paper, Bayesian Probability and Statistics Theory is used to evaluate the expected value of the mean parameter based on the fitting curve of probability density function. Taking a fractured rock slope in a power generation project in the coastal area of Fujian as an example, this method is used to optimize the slope safety slope angle.
