利用双轴贯入结合无侧限抗压试验方法与直剪试验方法,分别对不同含水量不同干密度下重塑黄土的抗剪性能进行测定,对比两种方法所测得的抗剪强度参数。结果表明:用双轴贯入结合无侧限抗压试验方法测得的抗剪强度指标C、φ值,通过一定的折减可用来表示土的抗剪强度参数,且两种方法测得的C、φ值随干密度增加而增加,随含水量增大而减小。 By using biaxial penetration combined with unconfined compressive test method and direct shear test method, the shear resistance of remolded loess with different water content and dry density was tested respectively. The shear strength parameters measured by the two methods were compared . The results show that shear strength index C and φ measured by biaxial penetration and unconfined compressive test can be used to express the shear strength parameters of soil by some reduction. The values ​​of C and φ increase with the increase of dry density and decrease with the increase of water content.
