  1. 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:在滿足一般力學原理和臨界狀態土力學理論的基礎上,本文將亞塑性理論與臨界狀態土力學相結合,推出了一個計算無粘性土靜止土壓力系數的理論公式.該公式形式簡單,僅與土的有效內摩擦角有關,其計算結果與常見的多個經驗公式的計算結果只有微小的差別.文中討論結果表明,該公式可用於確定無粘性土的靜止土壓力系數
