Conclusions
-
1.
The active earth pressure on retaining walls of finite length is considerably less than that determined by the Coulomb theory.
-
2.
The coefficient of pressure decrease depends on the soil parameters and ratio K=B/H. When K>5 the solution approximates the Coulomb solution.
-
3.
The slope angle of the slip plane of the soil for walls of finite lengthis greater than the angle determined by the Coulomb theory.
-
4.
The curves of intensity of the earth pressure have a curvilinear outline. The center of the pressure is located higher than under conditions of the two-dimensional problem.
