The different coefficients of stability of changing these factors are given , so the factors that are vital to the lateral stability of x - type arches are found , and the rationality of the methods taken to enhance the lateral stability of yesanhe bridge is evaluated 文中給出了各因素變化情況下的穩定安全系數,指出了對鋼管混凝土提籃拱穩定性有顯著影響的因素及其合理變化范圍,并對野三河大橋提高穩定性的措施的經濟合理性進行了分析。
The software ansys6 . 0 is used to analysis the stability of the state after construction of tongwamen bridge , linear method is used in analyzing the finite element model of the bridge , the coeffient of stability of different state after construction is given . on the basis , the effect of different factors such as the arrangement of lateral brace , the sloping angle of arch ribs , the stiffness of bridge deck system , the effect of non - orientedly conservative loadings of the hanger and tie bar etc is discussed . the different coefficients of stability of changing these factors are given , so the factors that are vital to the lateral stability of x - type arches are found , and the rationality of the methods taken to enhance the lateral stability of tongwamen bridge is evaluated 本文應用有限元分析商業軟件ansys6 . 0 ,采用線彈性方法,通過對該橋的空間有限元模型進行穩定性分析,得出其成橋運營階段各種工況下的穩定安全系數。在此基礎上,本文還通過有限元模型分析,就拱的矢跨比、吊桿(立柱)的非保向力效應、橋面系的剛度、橫撐布置形式、拱肋側傾角等因素對該橋整體穩定性的影響展開探討與研究。文中給出了各因素變化情況下的穩定安全系數,指出了對鋼管混凝土提籃拱橫向穩定性有顯著影響的因素及其合理變化范圍,并對銅瓦門大橋提高橫向穩定性的措施的經濟合理性進行了分析。
And the main contents of this dissertation are : ( 1 ) the engineering geological features of discontinuities in surrounding rock mass were analyzed on the basis of field geological survey and the preferred orientation of the main discontinuities were derived . then the displaceable blocks distributing on the roof and sidewalls of main chamber were searched out taking the intersecting relationship of discontinuities into consideration . then the failure mode and the coefficient of stability of the displaceable blocks were studied respectively 主要內容包括:在野外地質調查基礎上,通過統計分析得到地下廠區結構面的優勢方位;對結構面工程地質特性進行了分析;根據結構面的空間組合關系,搜索出可能在主廠房洞室的頂拱和邊墻部位出露的塊體,并分析了各塊體的可能滑移方式及其穩定性系數。
