| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
