摘　　要：大坝加高时最关心的是新老坝体结合面的模拟及其对坝体整体性和应力的影响,本文对新老坝体结合面进行温度与接触的直接耦合分析,真实模拟接触面力与热的传递机理,结果显示,随着温降值减小,新老坝体结合面之间接触压力增大,接触状态趋于闭合,并通过与整体计算方法对比,说明加高后坝体整体性良好。The simulation of the interface between the original and the heightened and thickened body is a key problem in the stress field analysis of arch dam. To simulate the transfer mechanism of force and thermal in the interface, a method of direct coupling According to the result of tracing the status becomes closer during illustrated that the stability of analysis between temperature and contact is presented in the entirety analysis. analysis course, the contact pressure of the interface increases and the contact the decrease of temperature drop. Comparing with the traditional method, it is the body renewed is close to a whole.
