重力式挡土墙变形影响因素研究

Research on the influencing factors of deformation of gravity retaining wall

对可能影响重力式挡土墙变形的因素进行了研究,通过大型通用有限元软件ANSYS分析了墙厚、墙高、墙面坡度、墙后堆载、墙前覆土对重力式挡土墙变形的影响情况,为挡土墙的研究提供了较为合理的分析方法。研究结果表明,墙厚、墙高、墙面坡度及墙后堆载是影响重力式挡土墙水平变形的主要因素,其中墙高及墙后堆载的影响尤其明显,而墙厚是影响重力式挡土墙沉降量的主要因素。

This paper researchs on the possible influencing factors to the deformation of gravity retaining wall,the universal finite element software ANSYS was used to analyze the influence of different wall width,different wall height,different wall slope,different soil-covered of front wall and different stacked heavy load to the deformation of gravity retaining wall.It provide a reasonable approach to the research of retaining wall.The results prove that the different wall width,different wall height,different wall slope and the different stacked heavy load are the major influencing factors to the horizontal displacement of gravity retaining wall,among them,the different wall height and the different stacked heavy load are more obvious.The different wall width are the major influencing factors to the largest settlement of gravity retaining wall.
