摘要
本文研究用变分法推导的有限深弹性地基双参数模型,提出了按照土中应力分布规律确定模型参数的方法,得到了有关计算公式和合适的边界条件。给出了相应基础梁的解析解,计算实例与理论分析吻合。
In this paper, the two-parameter model for a finite depth elastic foundation inferred by variational approach has been studied. For the first time, the regularites of compress stress distribution in an elastic foundation are used to determine the two parameters, and the related formulas and suitable .boundary conditions are gained. Analytical solutions for teams on this two-parameter foundation are proposed and the numerical results fairly conform to the theoretical analyses.
