Undrained Shear Strength of Frozen Unsaturated Silts

This study focuses on investigation of the undrained shear strength unsaturated frozen silts prepared at varying initial thermal and hydraulic conditions. The degree saturation controls ice unfrozen water contents temperatures below depression point. properties soils are highly influenced by which is coupled with state soils. To evaluate silts, a series direct simple experiments were performed using Bonny silt different degrees under monotonic loading. Compacted samples subjected to artificial freezing before loading stress-strain curves recorded during Identical sheared room for comparison. behavior was observed be significantly than those obtained where an average saturated higher 150% in comparison same soil condition. strengths also affected increase 142 % when increased from 0.51 1.00. results this will used ongoing investigations capacity deep foundations warming permafrost.
