摘　　要：对砌石拱坝加高培厚中的新、老坝体结构面,用有限元软件ANSYS结合接触理论进行计算,并分析结果得出:温升、水压力和淤沙压力使结合面上的接触压力增大,从而接触摩擦应力较大,有利于结合面的结合,而结合面在温降的作用下有脱离的趋势。Integrated with contact theory, the finite element method software ANSYS is used to calculate the interface between the new and the old mass of dam after the heightening and thickening of masonry arch dam. It is educed that increases in temperature, water pressure, and silt pressure result in the increases of contact pressure of the interface and the friction stress, thus it is beneficial for the binding between the interfaces, while the decrease in temperature disengages the interfaces.
