“…erefore, the key to solving the turfy soil problem is to establish the constitutive model that can reasonably describe its soil strength and deformation characteristics [9]. Experimental studies have shown that the stress history, stress pathways, and physical state of the soil, such as its composition structure, have a significant impact on its constitutive model [10][11][12]. Turfy soil contains a considerable degree of plant residue and organic matter, and the influence of the stress pathways on the constitutive model will be more significant because of the complexity of its composition and structure [13].…”

In recent years, highways have been built rapidly in China’s turfy swamp areas to accommodate economic development. Turfy soil is a type of special soil with high humus and incompletely decomposed plant contents, so its properties are complex and unique. Both the axial and confining pressures of turfy soil increase during embankment filling. Therefore, in this study, three soil tests for analysing the decomposition degree, organic matter content, and triaxial compression under confining and axial pressure increases stress paths were performed to achieve insights into the stress-strain properties of turfy soil. The volumetric and deviatoric strains of turfy soil were summarised to reveal the inner mechanisms of turfy soil, culminating in the establishment of a constitutive model for turfy soil. The results of the constitutive model were compared with the experimental test results to verify the accuracy of the constitutive model. The results showed that the stress-strain and strength of turfy soil are closely related to the organic matter content and decomposition degree. The calculated stress and strain results are also consistent with the experimental results, indicating that this constitutive model can be used to better indicate the original deformation state and strength characteristics of the turfy soil.

Los ensayos presiométricos ejecutados en sondeos han demostrado ser una herramienta eficaz en los estudios geotécnicos destinados a obras de infraestructura civil. Un aprovechamiento intenso del mismo, consiste en la comparación de sus resultados con los obtenidos de un modelo matemático gobernado por una ecuación constitutiva representativa del terreno. En ese artículo se presenta un modelo numérico, de anillos concéntricos, regidos por la ecuación constitutiva del Hardening Soil Model que pretende ser un marco de referencia para la interpretación del ensayo. El modelo analiza variables como son: los modos de respuesta, el estado inicial, el régimen de drenaje, y las ecuaciones constitutivas, pudiendo ser aplicado a cualquier formación geológica de la que se disponga de un número representativo de ensayos.
