本文所研究的粘土岩强度低、变形大,属于软岩。实验结果表明,其强度和变形模量与试块内含的结构体数密切有关。如起始流变应力σ_i=1.5+3.7/N~(0.37),极限破坏应力σ_c=5.1+14.5/N~(0.35)而对变形参数来说,亦具有类似的关系。
The claystones studied in this paper have low strength and large deformation and belong to soft rock. The experimental results show that its strength and deformation modulus are closely related to the number of structures contained in the test block. If the initial flow stress σ_i = 1.5 + 3.7/N ~ (0.37), the ultimate failure stress σ_c = 5.1 + 14.5 / N ~ (0.35) and the deformation parameters have a similar relationship.
