WebDesiccation crack is an important factor affecting engineering properties of clayey soils. In this study, the effects of compaction state and wetting-drying cycles on desiccation cracking behaviour of a clayey soil were investigated. Nine samples with various compaction water contents and dry densities were subjected to three wetting-drying ... WebMar 17, 2024 · Desiccation cracks have been observed in situ and in laboratory, respectively. Desiccation cracks are characterized in different clayey soils, for example, different layers of lacustrine clays, desiccated …
WebMay 30, 2024 · Desiccation cracking is a commonly occurring phenomenon in unsaturated soil with a high degree of saturation. The occurrence of soil desiccation cracking has a significant effect on the engineering properties of soils as it can considerably increase the hydraulic conductivity and decreases the shear strength of a soil [].Thus, it can pose a …
WebTherefore, it can be inferred that the desiccation cracks developed in two stages: the stage of rapid growth and stage of the steady state, in parallel with the increasing number of wetting–drying cycles.
