[摘要]新鄭國(guó)際機(jī)場(chǎng)T2航站樓尺寸巨大,建筑平面呈扁平的X形,地下有城際鐵路、市內(nèi)地鐵及城市下穿路通過(guò)?;A(chǔ)采用PHC高強(qiáng)預(yù)應(yīng)力管樁和后壓漿灌注樁,指廊因要求避免遮蔽塔臺(tái),故其建筑高度受限,為保證室內(nèi)凈空高度,屋面鋼結(jié)構(gòu)采用實(shí)腹H型鋼和四角錐鋼網(wǎng)架兩種結(jié)構(gòu)形式。主樓大空間部位采用了變截面錐形圓管四叉鋼斜撐支承鋼屋面,斜撐兩端采用鑄鋼節(jié)點(diǎn),為出發(fā)大廳創(chuàng)造了良好空間和視覺(jué)效果。

Abstract:Xinzheng International Airport T2 Terminal, which has huge size with flat Xshaped plane, has intercity railway, subway and urban underground road across the underground part. Foundation design adopts PHC highstrength prestressed pipe piles and post pressure grouting piles. The building height is restricted to avoid shielding the tower. In order to assure indoor headroom, roof steel structure design adopts two structural systems of solid web Hbeam and four pyramid space truss structure. The steel roof is supported by four cross steel brace of variable crosssection conical pipe in large space parts of the main building. Cast steel joints are adopted on both ends of the braces, creating a good space and visual effect for departure hall.
Keywords:Xinzheng International Airport; structure system selection; foundation design; cast steel joint; four cross steel brace
