EXPERIMENTAL RESEARCH ON LOESS DYNAMIC CHARACTERISTICS AT GROUND FISSURE BELT IN XIAN AREA

  • 摘要: 汾渭盆地是我国乃至世界上地裂缝最为发育,灾害最为严重的地区。考虑到地裂缝灾害对场地条件的影响,尤其是对场地土体的动力特性及动力响应的影响,本文在等压固结条件下,对西安地区地裂缝带黄土进行不同围压下的固结不排水(CU)动三轴试验,获取动力学参数,在此基础上分析了地裂缝带黄土动剪切模量随动剪应变变化特征曲线以及阻尼比随动剪应变变化特征曲线,并对所获得实验曲线进行回归拟合,进而建立了地裂缝带黄土的等效黏弹性动力本构模型,为进一步分析场地土体的动力响应奠定基础。
