A method for stress calculation on hardfill dam

An approach for the calculation on the stresses in the body of hardfill dam is put forward herein.The law of stresses distribution within the dam body is analyzed based on the result from the finite element method(FEM).On the basis of this,the methods for the calculations on the vertical normal stress,horizontal normal stress and shear stress therein are proposed.Through the demonstration from the actual case and the comparison with the result of the stresses calculated by FEM,it is proved that the method not only has a better precision,but is also convenient and efficient for the calculation,and then can satisfy the requirement from the preliminary analysis on the stresses within the body of hardfill dam.
