［摘要］對某客運站大跨度預(yù)應(yīng)力混凝土樓蓋結(jié)構(gòu)進行路面不平整度仿真分析、動力特性的現(xiàn)場實測和有限元軟件時程分析，采用基于信號檢測理論的煩惱率舒適度評價方法計算樓蓋的舒適度，并研究不同車輛荷載等因素對樓蓋舒適度的影響。由測試和有限元分析可得，最大計權(quán)均方根加速度和加速度極限值均滿足ISO規(guī)范對舒適度的要求。［關(guān)鍵詞］客運站; 大跨度樓蓋; 舒適度; 煩惱率中圖分類號：TU93+1， TV32+3 文獻標(biāo)識碼：A 文章編號：1002-848X(2015)17-0040-04

The comfort degree evaluation method of annoyance rate based on the signal detection theory was used to calculate the floor comfort degree, and the influences of different vehicle loads and other factors on the floor comfort degree were studied. According to the results of field measurement and the finite element analysis, the maximum weighted root mean square acceleration and acceleration limit value fulfill requirements of the ISO specification for comfort degree.Keywords:passenger station; large-span floor; comfort degree; annoyance rate
