中文摘要：
为研究不同计算模型的精确度及实用性,针对不同的反应位移法模型,以某明挖地铁车站为例,在不同地震作用下进行ANSYS建模计算,并与时程分析法计算结果进行对比分析,总结不同模型对结构内力的影响。发现反应位移法比经典反应位移法计算复杂,结果偏差较大;强制反应位移法计算量最小,但在地震作用较大时精度较低;整体反应位移法精度高、计算量小,用于明挖地铁车站的抗震设计可以提高工作效率和计算精度。
英文摘要：
To study the accuracy and practicability of different calculation models for response disphcement method, by taking an example of open-cut metro station construction, ANSYS modeling calculations were performed under the conditions of different earthquakes and the results were compared with the results of thne history analysis method. The influences of different models on the internal forces of the structure were summarized. It was found that the reaction displacement method and the classic response displacement method are both more complicated than other methods, and their results＇ deviations are also bigger; forced response displacement method has minimum calculation among all these models, but its accuracy is very low in large earthquakes; integral response deformation method has high precision and small amount of calculation, and it can improve the work efficiency and accu- racy when used in the metro stations constructed by cut and cover method.
