This paper presents a newly designed column-type experimental device for investigating the coupled thermo-hydro-mechanical behavior of expansive soils. Sensors and monitoring instruments facilitated continuous nondestructive measurements temperature, relative humidity, water content, total stresses in both axial lateral directions at various preselected locations device. The design features cal...

The nonlinear dynamics of the determining factors morphometric characteristics cracks in expansive soils make their typification a challenge, especially under field conditions. To overcome this difficulty, we used artificial neural networks to estimate crack Vertisol From July 2019 June 2020, soil (area, depth and volume), environmental (soil moisture, rainfall, potential evapotranspiration wat...

In 1968, Matyas and Radhakrishna introduced the concept of state surface, demonstrating that unsaturated soil volume change is dependent on two independent stress variables, net total suction. For decades basic theory soils has been known, a holistic view elastoplastic response soils, based modified surface approach (MSSA), makes it clear method accounting for roles suction required to quantify...

Expansive soils have high compressibility, swelling, and shrinkage properties. So we need an effective method to improve soil conditions when the structure is built on it. This paper presents results of research effect substitution ceramic waste physical properties expansive soil. Soil improvement using construction will contribute reducing amount conserving natural resources. The stages includ...

Engineering problems shunned previously rise to the surface gradually with the activities of reforming the natural world in depth, the problem of expansive soil crack under the changing environment becoming a control factor of expansive soil slope stability. The problem of expansive soil crack has gradually become a research hotspot, elaborates the occurrence and development of cracks from the ...
