摘要
本文通过在大型三向地震模拟振动台上进行的设置伸缩横缝的某拱坝非线性动力模型试验,应用非线性有限元动力分析程序同时进行计算分析,全面系统地研究了拱坝横缝对坝体动力特性和地震反应的影响,并对计算程序进行了改进。试验与计算结果相互印证,验证了试验成果的可靠性和计算分析模型、计算程序与计算结果的合理性。
In this paper the effects of contraction joints opening on dynamic behavior of arch dam have been studied thoroughly by carrying out model test on shaking table and corresponding nonlinear finite clement computation analysis. Furthermore some modifications on analytical method and computer program have been made. The experimental and analytical results clearly show that contraction joints open during the earthquake and the high tensile arch stresses are obviously reduced while the cantilever stresses arc increased to some degree. The two results are close to and definitely verified each other.
