| 英文摘要 | Loess contains numerous natural and artificial interfaces that exhibit complex mechanical properties and deformation mechanisms, making it prone to forming potential slip surfaces that influence its mechanical behavior. This study focuses on loess interfaces and employs cone penetration tests to clarify variations in cone tip resistance during penetration, utilizing finite element simulations to elucidate the underlying microscopic mechanisms. The findings demonstrate that the progression of cone tip resistance throughout penetration can be divided into three distinct stages: the initial, rapid increase, and the slow increase. Probe shape controls the initial stage, while the soil density ahead of the probe determines the transition in penetration rate. Terminal resistance throughout the penetration exhibits a inverse correlation with water content and is positively correlated with normal stress and dry density. Furthermore, interfaces weaken the terminal resistance. Higher dry density enhances the reinforcing influence of normal stress on terminal resistance. Although an increase in water content reduces the effect of normal stress on the terminal resistance of complete soil but enhances its effect on terminal resistance of composite soil. During penetration, the volumetric growth rate of the plastic zone in the soil increases from slow to fast. The high axial stress zones in the soil concentrated around the conical section of the probe. Axial stress shows a positive correlation with dry density and normal stress. In composite soil, the stress influence range is more significantly affected by dry density compared to complete soil. Interfaces significantly increase irregularity in the stress influence range. |
