effective angle meaning in English
of attack
有效角度
Examples
- Effective angle of internal friction
有效内摩擦角 - Abstract : on the basis of general principles of mechanics and critical state soil mechanics theory , a theoretical formula determining the coefficient of earth pressure at rest for cohesionless soil is derived by means of combining hypoplasticity with critical state soil mechanics . the formula has a simple form and is only related to the effective angle of internal friction of soil . there is a slight difference between the calculated value of the formula and that of other formulae . the further investigation of the formula shows that it can be used to determine the coefficient of earth pressure at rest of cohesionless soil
文摘:在满足一般力学原理和临界状态土力学理论的基础上，本文将亚塑性理论与临界状态土力学相结合，推出了一个计算无粘性土静止土压力系数的理论公式.该公式形式简单，仅与土的有效内摩擦角有关，其计算结果与常见的多个经验公式的计算结果只有微小的差别.文中讨论结果表明，该公式可用于确定无粘性土的静止土压力系数 - Then the judging method is proposed , and the proposed method can consider the stress history and viscosity shear strength of soft soil . in this paper , a fem program dpfbm1 . 0 ( double plastic foundation beam method ( version 1 . 0 ) ) is established . with this program , the influence of some parameters on foundation excavation is fully studied , the parameters include : compression modulus , cohesive strength , angle of internal ficiction , effective angle of internal friction , the embedded length of the wall and building load
