本文介绍一种新型抗滑支挡结构物的计算方法——弹性地基中刚架的差分分析。公式的建立是应用文克尔理论,根据差分原理,借助于材料力学和矩阵代数的基本知识完成的,并编制了电子计算机源程序,简单易懂,便于掌握。作者已将本方法应用于某工程的设计和地面以上普通刚架的计算,认为本方法是可行的。它不仅适用于地基层次多变和地基系数随深度成任意规律变化的情况,而且将该方法进一步延伸,还可解决其它较为复杂的地下结构物的计算问题。
This paper presents a new calculation method for anti-sliding support structure—differential analysis of rigid frame in elastic foundation. The establishment of the formula is the application of the Winkler theory, based on the difference principle, using the basic knowledge of material mechanics and matrix algebra to complete, and the preparation of the electronic computer source program, easy to understand, easy to grasp. The author has applied this method to the design of a project and the calculation of an ordinary rigid frame above the ground, and believes this method is feasible. It not only applies to the situation that the ground level is variable and the foundation coefficient changes with the depth to any law, but also extends the method, which can also solve the computational problems of other more complicated underground structures.
