Fe2O3和Al2O3胶结作用影响红粘土抗剪强度试验研究OA
Experimental Study on Influence of Cementation via Fe2O3 and Al2O3 in Red Clay on Its Shearing Strength
采用常规三轴试验,得到桂林地区红粘土的抗剪强度参数.由于红粘土中Fe2O3和Al2O3含量愈高,胶结作用愈强,导致红粘土的抗剪强度增加.通过线性回归拟合得出其百分含量和粘聚力成线性关系,并推导出拟合方程,以此评价Fe2O3和Al2O3胶结作用对桂林红粘土强度特性的影响.
In this paper, we get red clay's parameters of the shearing strength by conventional triaxial tests. As the content of Fe2O3 and Al2O3 in red clay is higher, the action of cementation is stronger, resulting in the increased shearing strength. The linear relation between the content in percentage and the cohesion may be obtained by linear regression fitting and then the fitting equation may be deduced, through which the influence of cementation via Fe2O3, Al2…查看全部>>
