趙華新，趙俊杰，譚麗華（北京城建設(shè)計(jì)研究總院有限責(zé)任公司，南京 210006）[摘要]介紹了地下車站抗震分析的主流計(jì)算方法—反應(yīng)位移法。以某實(shí)際工程為例，對反應(yīng)位移法中各參數(shù)、抗震分析模型、計(jì)算結(jié)果的調(diào)整方法進(jìn)行了詳細(xì)介紹。并對三座車站的計(jì)算結(jié)果進(jìn)行了對比分析，得出7度抗震設(shè)防區(qū)地震工況不控制板墻構(gòu)件配筋，但會影響中柱配筋。[關(guān)鍵詞] 地下車站；設(shè)計(jì)；抗震；反應(yīng)位移法中圖分類號：TU318 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2013)S1-1114-05Seismic design method and case analysis for underground stationZhao Huaxin1, Zhao Junjie1 , Tan Lihua1（Beijing Urban Engineering Design & Research Institute Co., Ltd., Nanjing 210006,China）Abstract: The response displacement method is introduced to the mainstream seismic analysis method of underground station. For example of the practical project, each parameter, the seismic analysis model and the adjustment method of calculation results were introduced in detail. The comparative analysis is made to calculate results of three underground stations. In the zone with the seismic fortification intensity 7, seismic conditions do not play a critical role in the reinforcement of panel and wall, but affect the reinforcement of column.keywords: underground station; design; seismic; response displacement method
