中文摘要:
      针对竖向荷载、水平荷载与力矩荷载共同作用下的条形基础,在塑性极限分析理论与Meyerhof “等效宽度”概念的基础上,构造可变的运动许可速度场,推导了复合加载模式下条形基础承载力的上限解.为了证实上限解的合理性与适用性,采用了通用有限元软件ABAQUS进行了数值计算.结果表明,推导的条形基础上限解能够很好地求解复合加载模式下地基的极限承载力.
英文摘要:
      Based on the Meyerhof′s effective width of strip footing and the plastic limit analysis theory, an upper-bound solution of strip footing under vertical, horizontal and moment loads due to combined loading is presented by constructing variable permissive moving field. In order to verify the rationality and applicability of this theoretical solution, numerical solution is achieved by using the general-purpose FEM analysis package ABAQUS. The results indicate that the upper-bound solution of strip footing due to combined loading is accurate to calculate the bearing capacity of foundation perfectly.
