A state-of-the-art review has been conducted in this work on soil constitutive modeling, which has emphasized on: soil type, ground-water conditions, loading conditions, structural behavior, constitutive relation discipline, and dimensions. By extension also, the soil constitutive applications were reviewed on the bases of: single discipline dealing with soil mechanical properties constitutive modeling which included slope stability problems, bearing capacity, settlement of foundations, earth pressure problems, soil dynamics, soil structure interaction, thermal and hydrological conditions; bi-discipline (coupled problems) which solve problems related to thermomechanical (freeze/thaw conditions), smoothed particle hydrodynamics (SPH) and hydromechanical (consolidation, collapse and liquefaction) conditions in soils and rocks and multi-discipline constitutive models which solve complex problems related to thermo-hydromechanical (THM) conditions in soils and rocks. This work has shown that smoothed particle hydrodynamics (SPH) and hydromechanical (HM) models, which belong to bi-discipline or coupled conditions are better suited for geotechnical applications, generally, while thermo-hydromechanical (THM) models, which belong to multi-discipline are better suited to solving freeze/thaw and thermal piles problems and these are proven with high performance and flexibility.
在这项工作中，对土壤本构模型进行了一次前沿综述，该综述重点关注了以下方面：土壤类型、地下水条件、加载条件、结构行为、本构关系学科以及尺寸。此外，还基于以下内容对土壤本构应用进行了综述：处理土壤力学性质本构模型的单一学科，其中包括边坡稳定性问题、承载力、基础沉降、土压力问题、土壤动力学、土-结构相互作用、热和水文条件；解决与岩土热机械（冻融条件）、光滑粒子流体动力学（SPH）和流体力学（固结、塌陷和液化）条件相关问题的双学科（耦合问题），以及解决与岩土热-流体-力学（THM）条件相关复杂问题的多学科本构模型。这项工作表明，属于双学科或耦合条件的光滑粒子流体动力学（SPH）和流体力学（HM）模型通常更适合岩土工程应用，而属于多学科的热-流体-力学（THM）模型更适合解决冻融和热桩问题，并且这些模型已被证明具有高性能和灵活性。
