基于反应位移法的现浇钢筋混凝土地下沟道抗震分析
|
摘要
在系统介绍反应位移法原理和计算流程的基础上,结合某电站具体工程进行了不同截面形式地下沟道的反应位移法抗震分析。概述了沟道设计分析过程的参数化实现方法,其中采用五点法实现了沟道中应力到内力的转化。对不同截面形式沟道的内力分布进行了具体的分析研究,绘制了截面的内力包络图,通过内力计算给出了配筋方案。计算得出的规律可以为地下沟道设计与施工提供依据,推动反应位移法在地下结构抗震分析中的应用。
In this paper,the response displacement method and calculation flow were introduced.The seismic analysis of response displacement method of underground channel with different cross-sections was performed in combination with some concrete power station project.Parameterized implementation method of the channel design analysis process was also introduced,in which the transformation of stress into internal force in channel was achieved by five-node method.The internal force distribution of different cross-section tunnel was researched and analysed,and envelope diagram of inner force in the cross-section of the tunnel was drawn.Reinforcement arrangement scheme was given through the internal force calculation.The regularity obtained from calculation can provide the basis for the design construction of tunnels,and promote the application of response displacement method in the seismic analysis of underground structures.
