# coefficient of earth pressureの例文

- Because the pile group effect exists , the
*coefficients of earth pressure* to the back piles reduce . p - y curve of pile group can be obtained by p - y curve of a single pile multiplied by a reduced coefficient - 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 - The authors suggest : the internal force ' s value is rational if the coefficient of lateral resistant force is one - forth to one - sixth of tests value , or the coefficient of lateral soil pressure is bigger than the
*coefficient of earth pressure* at rest , or the lateral resistant force is computed together with the lateral earth pressure
