等效内摩擦角 meaning in English
equivalent angle of internal friction
the equative angle of intemal fricion
Examples
- The retaining wall reclining on the slight slope built on soft foundation is usually used in protecting the shore of river , the contradiction between the lack of impartiality in stress of the base and the small stress allowed by the foundation as well as the lack of stabilization of the breast wall is a hard nut to crack in the engineering . in the paper , a tenon - base is added under the base of the retaining wall , on the study of the choice of the parameters and formulas used in calculation and the research of theory used in calculation , method used to deal with the load , etc , the writer gives a way to crack the nut mentioned above paragraphs and presents a qualitative and quantitative analysis about them , such as the equivalent inner friction - angle ( d ) and the passive press of the clay ( ep ) , etc . in the end of the paper , using modern optimization method , a design of the retaining wall reclining on the slight slope built on soft foundation is done , the result is economical , and accords with the fact
软基上的仰斜式挡土墙在水利工程河道护岸中经常遇到，仰斜式挡土墙基底偏心应力较大和软基土地基容许承载力偏小的矛盾以及挡土墙抗滑稳定不足是工程中难以解决的难题。本文在对仰斜式挡土墙设计中有关计算参数的选择、公式的选用应该注意的问题进行了研究，对河道护岸软基础上的仰斜式挡土墙采用凸榫基础处理的方法，就其计算理论、设计验算中各荷载的具体处理方法进行了较为细致的研究，提出了解决软基础上的水工仰斜式挡土墙难以解决的难题的方法，并对有水情况下粘土等效内摩擦角_ d 、凸榫被动土压力e _ p等在计算中的取值提出了定性和定量的分析。最后利用现代优化方法对软基础上的水工仰斜式挡土墙进行了结构优化设计，得出了符合实际的结果，与其它重力式挡土墙形式进行比较，取得了明显的经济效益。
