考虑施工质量影响的碾压混凝土坝地震动力响应
|
摘要
针对现有碾压混凝土坝地震动力响应分析未考虑施工质量影响的问题,提出一种考虑施工质量影响的碾压混凝土坝分析方法。基于碾压混凝土坝施工质量实时监控系统数据,分析施工质量对物理力学参数的影响;建立考虑施工质量影响的有限元分析模型,并结合实际工程,进行地震动力响应计算。结果表明,该方法可以分析施工质量对地震动力响应的影响,为抗震设计提供科学依据。
The design values of the materials' property parameters were adopted customarily in researches by far, which failed to take the influences of construction quality into account. A method for the seismic response analysis of RCC dam considering the influences of construction quality is proposed in this paper. Firstly, based on the real-time monitoring data of compaction quality of RCC dam, the physical and mechanical parameters under the impact of construction quality were analyzed; then, a finite element model considering the influences of the construction quality was established; finally, combined with a practical project, the seismic responses were calculated. The results show that the influences of the construction quality on the seismic responses can be analyzed with this method, and thus, it can provide more scientific evidences for the anti-seismic design of RCC dam.
