“…Silty clay, a soil type characterised by low thermal conductivity and pronounced rheology, is extensively utilised in diverse sectors, encompassing civil and environmental engineering to underground energy storage [1,2]. Its favoured status in foundational constructs, subterranean tunnels, and soil barriers underscores its pivotal role [1,2]. However, the intricate internal structure and variegated pore distribution have rendered the accurate prediction of its thermal conductivity and thermal stress behaviour formidable [3][4][5][6].…”

Silty clay, pivotal in domains spanning civil and environmental engineering to underground energy storage, demands precise characterisation of its thermal conductivity and shear strength. Root reinforcement has recently been heralded for its eco-friendly attributes and efficacy in enhancing soil properties. Nonetheless, extant literature remains focused on individual soil types, often sidelining the biological influence of entities like roots. Moreover, a reliance on experimental measurements in prior studies has precluded exhaustive theoretical discourse. Addressing these lacunae, the present investigation was embarked upon. Two focal areas emerged: firstly, an intricate exploration, underpinned by both experimental and simulated data, of the correlation between pore attributes and thermal conductivity in root-reinforced silty clay, and the concomitant repercussions on shear strength. Secondly, an encompassing appraisal of the thermal stress within this reinforced clay was conducted via a temperature-seepage-stress coupling model. Marigold root-soil composites became the central subjects, with an aim to discern the influence of herbaceous Asteraceae plants endemic to Taihang Mountain on parameters such as erosion resistance, soil consolidation, and shear resistance augmentation of soil masses. By harnessing raw soil samples, fashioning test specimens, and executing controlled triaxial compression experiments, intricate patterns pertaining to erosion resistance and soil consolidation, modulated by varying factors like root content, soil depth, and moisture content, were elucidated. The revelations herein promise to refine predictions of thermal conductivity and deepen the comprehension of shear strength dynamics in multifaceted soil scenarios.

Soil investigation is very important to check the bearing capacity before constructing any structure. There are different types of soils that cause many problems for the structure in short and long term, which are known as problematic soils. A lot of researchers dealt with improvement and reinforcement of the problematic soils by physical and chemical treatments. The objective of this study is reinforcing the problematic soil with micropiles with different depths and different configurations. In this study, two types of soils, soft clay and loose sand, were used to study the effect of adding micropiles of different depths and different configurations to investigate the best improvement of bearing capacity for shallow foundations on these soils. The results showed that reinforcing the natural soil with micropiles could improve the pressure carrying capacity of the problematic soils. When the design width is changed from under foundation alone to under foundation and 2B width, the soil reinforced with 2B depth of micropiles can raise the soil’s load carrying capacity by 45 to 65% when compared to untreated soil. Just 7% more bearing capacity may be achieved by increasing the depth of the micropiles from 2B to 3B (where B is the footing width); as a result, going deeper than 2B is not advantageous. Additionally, the bearing capacity of the micropiles increases by only 3% when the breadth of the configuration is increased from 1B to 2B; so, wider configurations than 1B are invalid.

Ground hydrocarbon contamination is a grave consequence of fossil fuel consumption, making it increasingly unsustainable. Consequently, researchers worldwide have been compelled to conduct a large number of studies on the geotechnical aspects of hydrocarbon-contaminated soils. Still, the complications arising from the integration of geotechnical complexities with diverse hydrocarbon properties present a substantial research need. The assessment of the foundation bearing capacity in hydrocarbon-contaminated soils is of paramount importance, especially given that numerous contaminated sites either house significant industrial facilities or are earmarked for critical infrastructure projects. This study investigates the shear strength and bearing capacity of gas oil-contaminated coastal sands using laboratory testing and physical modeling, with a special focus on the combined influence of the degree of saturation and relative density. Footing’s shear failure mechanisms were analyzed based on predicted and measured bearing capacity values. Findings show a decrease in the friction angle with a contamination increase, while the apparent cohesion initially rises before declining. Furthermore, the study revealed that the foundation’s bearing capacity exhibited an increase up to a specific contamination level, followed by a subsequent decrease. This increase is circa 90 and 100 percent at a 5 percent contamination content for loose and dense sand, respectively. Comparing the predicted and measured bearing capacity results shows that the general shear failure mechanism has occurred in the dense subgrade, while the loose subgrade’s failure mechanism is more inclined towards local shear failure.
