Strength Analysis of Weak Bottom Soil of Road Embankments
Abstract
The paper deals with the practical method of calculating the bearing capacity of weak bottom soil of road embankments. A theory of soil limit equilibrium underlies this method. A direct force action produced by the embankment on the soil represents the pressure with a trapezoid diagram of the normal component. Closed solutions are considered for an ideal-cohesion and weightless bottom soil. Approximation formulas obtained for the general case, are based on results of numerical calculations. The influence of a rigid layer is estimated for the bearing capacity of the bottom soil. Equations are obtained for the limiting pressure of embankment on the weak soil depending on soil characteristics and geometrical parameters of embankment.
