“…e first method is to correlate digital images with software, for example, VIC-3D [25], which allows measuring the vertical displacement directly. Another solution to determine the vertical displacements is to measure them with a laser [55], a Vernier caliper [56], or other devices.…”

Cracks in clayey soils are common during desiccation. The presence of cracks significantly alters the mechanical and hydraulic properties of soils. The objective of this article is to summarize the works on cracking behavior and mechanism in clayey soils related to desiccation. Historical field investigations, laboratory experimentations, identified mechanisms, and numerical approaches for modeling the process of cracking during desiccation are discussed. The experimental approaches for interpreting the mechanisms of cracking are systematically summarized and comprehensively reviewed based on the in situ observations and laboratory experimentations from the literature. The soil mechanics-based approaches resumed in this article according to the fracture mechanics theory and numerical results highlight the cracking development mechanism. Concerning the plasticity characteristics of clayey soils, researches on soil fracture mechanics should be paid more attention. More in situ experimentations and numerical researches are suggested for future researches to better understand the cracking behavior and mechanism in clayey soils related to desiccation.

Quantitative and qualitative determination of total volume and surface features of a soil specimen is important in geotechnical engineering. Available methods suffer from a variety of shortcomings such as sample disturbance, equipment calibration, and lack of precision. The Controlled Photogrammetry System (CPS) is based on Structure-from-Motion (SfM) to capture a series of photographs and transform the images into a referenced three-dimensional model. • This paper develops the Controlled Photogrammetry System. • This paper describes the design and operation of the Controlled Photogrammetry System. • This paper presents data processing and test results for a sand and clay.

“…In addition, some modelling and theoretical studies on desiccation cracking have also been investigated. However, the essential mechanism of desiccation cracking is still not well understood, and the ability to predict the initiation of cracking and subsequent crack network propagation also faces several challenges [12][13][14][15][16].…”

Expansive Clay Cracking Behavior through Digital Image Correlation

et al. 2020

Expansive soils may present cracks arising from the drying process and their evolution can cause irreparable damages to engineering projects. Investigating this phenomenon is vital to understanding its geomechanics. The objective of this article is to present numerical modelling of the formation and propagation of cracks in expansive soil. A desiccation experiment was therefore carried out using an expansive silty clay from Paulista, in northeastern Brazil. The drying process was monitored by measuring the temperature and relative humidity of the air, as well as by capturing images with a camera. The digital images were correlated using the Ncorr numerical tool in MATLAB. As a result, this study made it possible to conclude that the soil cracking dynamics presented a non-orthogonal pattern during the dryness test, while the image treatment made it possible to observe the tendency of cracks to appear and propagate on the soil surface, allowing for the detection of crack growth and propagation trends.
