论有效应力原理在土力学教学中的核心地位

Key influence of effective stress principle on teaching practices of soil mechanics

土力学的研究对象为固、液、气三相介质,且三相介质间存在着复杂的耦合关系,这种情况决定了土力学内容体系的庞杂性与学科发展的相对低水平性。有效应力原理在土力学本科生和研究生的教学中具有重要的核心作用,是土力学的灵魂,能把土力学中各零散的知识点有机地串接交织在一起,土力学教材知识体系实际上是对有效应力原理进行完整地解释与理解的知识体系。所以,深化对有效应力原理的理解是进一步提升教学质量的关键。

Soil mass is a mixture, including solid phase（ soil grain）, liquid phase（water）, gas phase（gas）, and involving three phases multi-coupling interactions, so this situation decides soil mechanics relative lower development level and multi-channel knowledge systems coming from other concerning subjects at present. In spite of this, effective stress principle, which makes separate concepts, knowledge points, and different theories connected together successfully, plays a key role during soil mechanics teaching practices for under graduate and post graduate students. Soil mechanics textbook knowledge system, as a matter of fact, is a continuous process covering understanding, explanation, and application of the effective stress principle in geotechnical engineering practices. Thus, further deepening understanding the effective stress principle is a very key issue about improving soil mechanics teaching quality for students.
