经典土压力理论 meaning in English
classical earth pressure theory
Examples
- This general form leads to the unification of coulomb ' s earth pressure theory and rankine ' s earth pressure theory , and makes the classical earth pressure theory to consummate , and enables the computation for retaining wall ' s engineering design to be more convenient
一般形式的提出，使朗肯土压力理论和库伦土压力走向统一，使经典土压力理论得以完善，使挡土墙工程设计时的计算更加便捷。 - With the help of this program , this paper does research on the moved backwards of the slide surface , lengthening the anchor section , the soil nail ' s total force , gets conclusion about relations between the soil nail ' s length and the slope ' s grade , height , soil ' s mechanical parameter ; relations between soil nail ' s total force and coulomb soil pressure . with the help of the large multiuse finite element program ansys , this paper analyzes the soil nailing in one - step ' s slopes , in two - steps " slopes , puts the emphasis on the axis force ' s distributing along the soil nail at each rows , the effect of both the excavating mode and the original slope figure to the axis force of the soil nail , the one another effect between the upper - step slope and the nether - step slope in the soil nail ' s axis force , gets conclusion about the design of soil nail at the first low , different slope body is the same with different excavating mode , the original slope figure has more effect to some than others because of the slope body , the reasonably design of the step width in two - steps slopes , the two - steps excavating and retaining has more virtue than the one - step ' s . through soil pressure analysis this paper does research on the differences and the links between the coulomb soil pressure theory and the rankin ' s , the vertical pressure at the slope surface when the slope surface is inclined and the retaining wall is rough , the soil pressure ' s distributing behind the panel , gets conclusion about the effect of both the slope body inner stability and the slope surface local stability to the soil pressure
通过分析比较，论证了对数螺旋线型比圆弧形作为边坡的假设滑裂面具有较多的工程优点，并为此编制了一个采用极限平衡法分析土钉支护的fortran语言程序，以此作工具对滑裂面的后移、土钉锚固段的超长、土钉总力的大小等方面作了研究，得出了有关土钉的长度与边坡的坡角、坡高、土体力学参数的关系、土钉总力与库仑土压力间的关系等结论；采用大型通用有限元数值分析程序ansys分别对采用土钉支护的一阶边坡、二阶边坡进行分析，重点是研究各排土钉的轴力分布规律、开挖方式及原始边坡形态对土钉的轴力的影响、上下阶边坡在土钉轴力方面的相互作用，得出了有关第一排土钉的设计问题、不同类型的土体应适用于特定的开挖方式、原始开挖出的边坡形态对一些类型坡体的边坡土钉支护有较大的影响而对另外一些影响不大、二阶边坡台阶宽度的合理确定、二阶开挖及支护比一阶时具有较多的工程优点等结论；通过土压力分析对朗肯、库仑两种经典土压力理论的区别与联系、坡面倾斜及墙背有摩擦时的坡面竖向应力分布、面板背土压力的分布形态作了研究，得出了边坡支挡土压力受坡体内部稳定与坡面局部稳定两个方面的影响、土钉支护面板背土体中卸荷拱的存在对面板受力有利等结论。
