根据小浪底工程进水口孔板泄洪洞进水塔的结构布置型式及操作运用要求,采用了拟静力法、非线性稳定分析及反应谱法有限元动力分析对孔板塔的整体稳定性进行了分析,并作了抗震动力模型试验。结果表明,孔板塔的结构布置是经济、合理的,其结构整体稳定是有保证的。
According to the structural layout and operating requirements of the inlet tower of Xiaolangdi Project, the quasi-static method, nonlinear stability analysis and response spectrum finite element method are used to analyze the overall stability of the perforated tower Analysis, and made a seismic model test. The results show that the structure of perforated plate tower is economical and reasonable, and its overall structural stability is guaranteed.
