摘要

基于沥青混凝土的动力三轴试验资料，建立了相应的动力计算模型。采用三维有效应力动力分析方法，结合即将开工的某沥青混凝土心墙堆石坝，利用TSDA程序计算分析了坝体的加速度、动应力反应和大坝的地震永久变形，并对坝基细砂层在地震过程中的液化问题进行了研究，认为沥青混凝土心墙具有良好的抗震性能，大坝在地震过程中是安全的；坝基砂Ⅲ层可能发生液化，需要进行加固处理，分析结论可供同类工程建设参考。

Abstract

Based on dynamic triaxial test data of asphalt concrete

a dynamic constitutive model is suggested. By 3-D dynamic effective stress analysis method

combining with an asphalt concrete core rockfill dam to be built

seismic responses of acceleration

dynamic stress

seism-induced permanent deformation and seism-induced sand’s liquefaction are analyzed by using TSDA program. The dam is safe because of well aseismatic performance of asphalt concrete core

third-layer sand in the alluvium may be liquefied and need be reinforced.The conclusion could be referred to the analogous engineering.
