【摘要】 选取湖北省巴东县黄土坡1#崩滑体为研究对象,设计了滑带碎石土在不同含石量(40%、60%、80%)、不同含水率(11%、17%、23%)条件下的大型直剪试验。通过Matlab的数值拟合,随机-模糊理论的数值拟合和BP神经网络预测等方法对滑带土抗剪强度进行分析。确定滑带碎石土在不同含石量、不同含水率及不同级配条件下的抗剪强度参数,探讨选取滑带土抗剪强度参数的最优方法。更多还原

【Abstract】 1~# slumped mass of Huangtupo in Badong County,Hubei Province was selected as the research object, a large direct shear test of slippery gravel soil under different stone contents(40%,60%,80%) and different water content(11%,17%,23%)was designed.The shear strength of sliding zone soil was analyzed by numerical fitting of Matlab,numerical fitting of random-fuzzy theory and BP neural network prediction to determine the shear strength parameters of the slippery gravel soil under different rock content,different water content and different grading conditions and discuss the optimal method for selecting the shear strength parameters of the sliding zone soil.更多还原
