“…The results showed that oil pollution led to the deterioration of the geotechnical properties of the soil samples. Compared with raw soil, its maximum dry density, optimum water content, permeability, and shear strength decreased [6][7][8]. The particle size distribution and density of soil samples have a great impact on the mechanical properties and permeability of oil-contaminated clayey silt.…”

Flood-controlled ancient dikes play a significant role in flood control and have received widespread attention as historical and cultural symbols. Flood-controlled ancient dikes often undergo disasters, and research on their repair is receiving increasing attention from experts and scholars. This article studies the control of seepage and bank slope instability in flood-controlled ancient dikes. Starting from the repair of ancient dike materials, three types of work are carried out: a test of soil’s mechanical properties, finite element numerical simulation, and repair technology research. The research results show that the soil of the ancient dike site has hardened after being contaminated with waste oil from catering. The strength index of the ancient dike soil decreases and shows brittleness when the water content is 15% and the oil content exceeds 6%. The strength index and permeability coefficient of oil-contaminated soil improved using modified lime mortar (MLM), which was achieved using the method of MLM to repair oil contaminated soil. When the MLM content was 10% and the oil content was 6%, the friction angle of the soil sample reached its maximum value. When the MLM content was the same, the higher the density of the soil sample, the greater the friction angle and cohesion and the smaller the permeability coefficient. Establishing a finite element numerical model, through comparative analysis, it was found that after MLM remediation of oil-contaminated soil, the extreme hydraulic gradient of the ancient dike decreased by 31.3%, and the extreme safety factor of the bank slope stability increased by 31.2%. MLM pressure grouting technology was used to improve the soil during the remediation of contaminated soil at the ancient dike site. Through on-site drilling inspection, the effective diffusion radius of MLM grouting was obtained, and the plane layout and grouting depth of MLM pressure grouting were determined. The on-site water injection permeability test showed that using MLM pressure grouting technology can effectively repair oil-contaminated soil in the ancient dike while reducing the permeability coefficient by 8–15%.

“…Additionally, stone dust is pozzolanic in nature and includes coarse particles not seen in other admixtures such as fly ash. Numerous research studies were carried out for soil stabilization, the results show the significant positive impact of waste on soil properties [9]. Since, we are in the contemporary industrial age, with the fast development in the industrial zone, we must look for new additive materials, including modern wastes that will enhance our wellbeing while simultaneously causing negative consequences such as health issues and pollution.…”

This research paper depicts the experimental investigation of the impact of stone dust as an admixture on the geotechnical characteristics of expansive soils that shrink and swell during the wet and dry seasons. As a result, expansive soil causes the differential settlement of structures. Thus the stabilization of expansive soil is important to overcome potential pavement failure. For this purpose research studies were carried out on the reuse of stone industry wastage for the improvement of expansive soil. Also, this research is beneficial to utilize the stone dust waste for strengthening the soil and making the environment pollution-free. Stone dust was used to stabilize the geotechnical characteristics of the weak soil such as shear strength, unconfined compressive strength (UCS), index properties, maximum dry density (MDD), optimum moisture content (OMC), and California bearing ratio (CBR). The percentages of stone dust employed in the studies were 0%, 7%, 14%, 21%, and 28% by dry weight of soil, which substantially reduced the soil's swelling properties. The results show significant improvements in the desirable geotechnical characteristics of the expansive soil. The optimal quantity of stone dust was concluded based on the findings for treating the subgrade of weaker expansive soil.

“…Xie et al [23] and Li et al [24] performed an unconfined compressive strength test to study the strength and deformation characteristics of oil-polluted coastal saline soil samples by mixing oil with coastal saline soil of known water content. Iqbal et al [25] carried out a series of laboratory tests to study the permeability and mechanical properties of low plastic soil. Based on the abovementioned studies, the physical-mechanical behaviors are relatively complex for different types of soil, such as finegrained soil, clay, and kaolin soil.…”

Oil leakage will not only pollute the soil but also change its physical-mechanical behavior, and loess has complex properties in the environment of oil presence. Artificial loess contaminated by diesel oil is collected as the research object. The physical and mechanical properties of clean loess and contaminated loess, including liquid and plastic limits, permeability, compression properties, and compressive strength characteristics, are estimated through a series of laboratory tests under different oil contents, water contents, and dry densities. Results show that liquid limits, plastic limits, and permeability coefficient of diesel-contaminated loess decrease with the increase of oil content. The compression modulus and compressive strength of diesel-contaminated loess increase with the increase of dry density at the same oil content. Adding diesel oil, the change law of the unconfined compressive strength of contaminated loess is opposite at the two different water contents. The variation of the compression modulus and unconfined compressive strength of diesel oil-contaminated loess is basically identical at the same condition. The findings of this study would be expected to bridge the gap between theory and practice in treatment and remediation of contaminated soil in the region of oil production.
