在基础工程设计原理课程教学中,学生经常对柱下独立基础冲切与剪切概念产生困惑。文章针对这一问题,从破坏机理、破坏面形式以及破坏性质等方面对冲切和剪切的概念进行分析,通过分析比较国家以及地方相关规范规定,并结合具体算例阐明了冲切和剪切的基本概念,有利于教学中学生对相关概念的理解。

In the course of design principles of foundation engineering, students are often confused by the concept of punching and shearing of independent foundations under columns. To clarify this problem, we analyzed the failure mechanism, forms of failure surface and failure characteristics. The provisions of relevant codes were compared together. Two specific examples were also introduced to clarify conceptions of punching and shearing. The analysis in this paper will be helpful to students to understand some basic concepts in the teaching process.
