摘　　要：研究提出一种Hardfill坝坝体应力的计算方法。根据有限单元法计算结果,分析了Hardfill坝坝体应力的分布规律,在此基础上总结提出坝体铅直正应力、剪应力及水平正应力的计算方法。通过实例验证并与有限单元法的应力成果对比,证明本文提出的计算方法具有较好的精度,计算方便快捷,可以满足对Hardfill坝坝体应力初步分析的需要。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.
