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(wěn)定安全系數(shù),指出了對鋼管混凝土提籃拱穩(wěn)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(wěn)定性的措施的經(jīng)濟(jì)合理性進(jìn)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(yīng)用有限元分析商業(yè)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(jìn)行穩(wěn)定性分析,得出其成橋運營階段各種工況下的穩(wěn)定安全系數(shù)。在此基礎(chǔ)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(yīng)、橋面系的剛度、橫撐布置形式、拱肋側(cè)傾角等因素對該橋整體穩(wěn)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(wěn)定安全系數(shù),指出了對鋼管混凝土提籃拱橫向穩(wěn)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(wěn)定性的措施的經(jīng)濟(jì)合理性進(jìn)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(nèi)容包括:在野外地質(zhì)調(diào)查基礎(chǔ)上,通過統(tǒng)計分析得到地下廠區(qū)結(jié)構(gòu)面的優(yōu)勢方位;對結(jié)構(gòu)面工程地質(zhì)特性進(jìn)行了分析;根據(jù)結(jié)構(gòu)面的空間組合關(guān)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(wěn)定性系數(shù)。
