（煤炭工業(yè)部太原設(shè)計研究院 030001）[提要] 通過49m×lOOm，45m×81m，60m×117m三個雙層柱面網(wǎng)殼在不同結(jié)構(gòu)形態(tài)、各種支承條件及輕、重屋面荷重下的計算分析，對柱面網(wǎng)殼結(jié)構(gòu)選型、計算假定等作了詳盡的論述；并討論了對于柱面網(wǎng)殼支座水平推力的處理、溫度應力對大跨度柱面網(wǎng)殼的影響等不能回避的問題，指出網(wǎng)殼支座與平板網(wǎng)架支座節(jié)點的不同，提供了常見支承條件下網(wǎng)殼支座的設(shè)計思路和作法。
[關(guān)鍵詞] 雙層柱面網(wǎng)殼 選型 溫度應力 水平推力Based on the design and research of three double-layer barrel vaults, authors give the structral style selection, the method of analysis and calculation plans. Also, static force characteristics of the barrel vault under different kinds of plans are analysed. Finally, the effects of temperature stress and horhontal support reaction are discussed.
Keywords: double-layer barrel vaults; style selection; temperature stress; horizontal support reaction
