Desiccation cracking
WebOct 10, 2009 · Air drying of initially saturated soil slabs in controlled conditions is investigated by performing three kinds of tests: free desiccation tests, constrained desiccation tests (prevented... WebCohesive crack approach is presented as a viable approach for modelling of desiccation cracking and fracture evolution catering for consistency change of soil during desiccation. It is highlighted that both tensile strength and crack opening displacement increases, thereby increasing the fracture energy of the soil as the moisture content reduces.

WebNov 9, 2024 · Desiccation cracking of soil is a common phenomenon in such regions. The formation of soil desiccation cracks due to moisture evaporation and volumetric shrinkage is frequently observed in drying climatic regions (Fig. 1 ). WebFive desiccation cracking tests for slurried clay soils were carried out using shrinkage moulds in a humidity chamber, which was capable of controlling relative humidity and temperature. The soil used in the experimental studies was residual basaltic clay and was classified as a highly reactive soil.
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 … WebMar 17, 2024 · Desiccation cracks have been observed in situ and in laboratory, respectively.
