Pragmatism and soil mechanics

  • 摘要: 通过对有效应力原理、强度准则、地基沉降计算、本构关系模型、非饱和土以及工程中土的参数等方面的论述,说明了土力学的实用主义特色;指出土作为一种十分复杂的材料,土力学作为一门感性很强的实用的学科,研究者应立足于工程实用,密切结合实际,不惮于亲自参与工程实践,才能认识和理解土力学与土工实践中实用主义的有效性和必要性,才会获得切实的成果,为岩土工程作出贡献。也同时指出了实用主义的局限性,它常常与经验主义为邻,因而土力学的概念和理论是不容忽视的。
    Abstract: According to the recount and analysis about the principal of effective stress, strength criterion, settlement calculation, constitutive model, unsaturated soil and calculation parameters in engineering practice of soils, it is drawn that the pragmatism is a characteristic and effective work method in the subject of soil mechanics. The soil is a very complex kind of material, and soil mechanics is a practical subject. Therefore, the researches on the soils have to be based on engineering application because of the pragmatism characteristic of soil mechanics. The pragmatism and empiricism are often interlinked with each other, and the concept and theory in soil mechanics are not allowed to be overlooked.
