（中國建筑西南設(shè)計研究院 成都 610081）[提要] 德陽市體育館根據(jù)建筑造型及功能要求，屋蓋采用了雙曲拋物面雙層鋼網(wǎng)殼結(jié)構(gòu)。屋蓋投影平面呈菱形，邊長74. 67m，對角線長105. 60m。通過對雙層網(wǎng)殼結(jié)構(gòu)的受力特點，桿件布置形式，網(wǎng)殼厚度的確定及嗍殼與懸索結(jié)構(gòu)對邊緣構(gòu)件的影響等方西的論述，闡明了結(jié)構(gòu)設(shè)計方案的確定原則。另外進行了結(jié)構(gòu)內(nèi)力分析，并介紹了支座構(gòu)迸，鋼材{商標等。
[關(guān)鍵詞] 雙曲拋物面 網(wǎng)殼 曲西方程 邊緣構(gòu)件Deyany Stadium of Sichuan Province, having a plan of lozonge with the side of 74. 67m long and with the diagonal of 105. 60m long, adopts double-curved and double-layered parabola steel roof structure, based on its architectural form and functions. The theme, from the force-bearing double-layered network structure, layout of members, thickness of network anci network roof structure and suspended cable are affecting on side members, embodies the rules of deciding structure scheme in addtion to analysize the inner structural forces and to introduce the support strcture and steel specifications.
Keywords: double-curved parabola roof; network roof; orthogonality; curved surface equation;
