基于改进均值滤波的多响应面法高陡边坡可靠度分析
|
摘要
采用改进均值滤波法对多响应面法进行改进,构建了基于空间滤波的多响应面法消除多响应面子区域交接处的突兀点,提高可靠度计算精度和计算效率。用matlab语言编程实现改进后的空间滤波多响应面法应用于永吉县西阳河高陡边坡可靠度计算。结果表明,采用改进均值滤波法对多响应面法计算精度明显提高,适用于大型复杂边坡工程的可靠度计算。
The multi-response surface method is improved by the improved mean filtering method,and a multi-response surface method based on spatial filtering is constructed to eliminate the abrupt points at the junction of multi-response face regions so as to improve the accuracy and efficiency of reliability calculation.The improved spatial filtering multi-response surface method is programmed with MATLAB language and applied to the reliability calculation of high and steep slope of Xiyang River in Yongji County.The results show that the accuracy of the multi-response surface method is obviously improved by using the improved mean filter method,which is suitable for the reliability calculation of large and complex slope engineering.
