基于分层总和法的地基沉降计算教学反思

Teaching reflection in the foundation settlement of layer-wise summation method

目前,工程中计算地基沉降常使用规范推荐方法,而各类土力学教材所用的方法却不尽相同,或者直接介绍分层规范推荐方法,或者根据分层总和法的基本原理进行讲解。总体而言,各类教材对此处知识点的介绍侧重不同,对沉降计算整体知识框架关注不够。通过比较规范推荐方法与土力学教材中常用的一般原理法,建立两种方法的联系,同时进行教学反思,以期找到一种更好的教学方法,从原理上讲解工程中所使用规范方法的具体内涵,帮助学生理解沉降计算知识体系。

At present, recommended methods of standard documents have been wildly used in foundation settlement. But teaching materials of soil mechanics choose different methods as the examples, which introduce recommended methods of standard documents directly or only pay attention to the principle. Above all, the attention of the foundation settlement frame is lacking, which cannot be drawn both to the recommended methods and the principle. Under this circumstance, a kind of new teaching method is put forward which connect recommended methods and the principle and keep a watchful eye on both, helping students understand the frame of foundation settlement.
