考虑土与结构共同作用的挡土结构内力和变形

Internal Force and Deformation of Resisting Structure with Interaction between Soil and Structure

分析了作用在挡土结构上的土压力产生的机理,指出土压力应分为两部分:一部分产生于开挖卸载,另一部分产生于挡土结构位移.提出了一种考虑挡土结构与土体共同作用的分段弹性地基梁分析方法.

In this paper, the mechanism of soil pressure on resisting structure is analyzed. It is pointed out that the soil pressure should be divided into two parts, one part caused by excavating and unloading, the other caused by displacement of resisting structure. The elastic ground beam subsection-method with interaction between soil and structure for resisting structure analysis is developed.
