摘要

对比研究了瞬态热传导方程和孔压增长消散方程，提出了一种利用ANSYS温度—结构耦合场进行土石坝有效应力动力分析的方法，这种方法通过动态调整材料参数，使总应力分析更加贴近实际情况，因此是一种改进的TT方法。这种方法具有很好的计算稳定性，适合用于长持时的地震反应分析。最后，利用这种方法对对云龙水库心墙堆石坝进行了动力计算，得到了有价值的结论。

Abstract

After comparing the transient heat conduction equation and the pore pressure generation-dissipation equation

this thesis presented a simplified method

basing on which we could apply the thermal-structure coupled field module of ANSYS to analyze the dynamic response of earth-rock dam conveniently. This method is similar to TT method

though

it is more appropriate to call it an improved TT method

because in this method the mechanical parameters of the soil materials are adjusted continually to simulate the coupled effect between the distortion of the soil skeleton and the dissipation of the pore pressure

which leads to a more precise simulation of the real condition. Finally

this approach was applied to calculate the three-dimensional seismic response of the earth core rockfill dam of Yunlong reservoir; and some valuable conclusions were drawn.
