They had never been worn, my mother said. under that, the miscellany began - a quadrant, a tin canikin, several sticks of tobacco, two brace of very handsome pistols, a piece of bar silver, an old spanish watch and some other trinkets of little value and mostly of foreign make, a pair of compasses mounted with brass, and five or six curious west indian shells
在那套衣服的下面，開始出現了各式各樣的東西：一個四分儀，一個錫制的小酒杯，幾顆煙，兩對非常漂亮的手銑，一根銀條，一隻西班牙老懷表，還有其他一些不值錢的小裝飾品，大多是外國製造的，一副黃銅桿的圓規，還有五六個珍奇的西印度貝殼。 -
Secondly, this paper made some theoretic researches on its engineering classfication and applicable scope for this technology ; then combining with project example, this paper carried out scheme design for this technology, and compared some different kinds of underpinning scheme and node and structure design, and put forward the method of " reinforcce steel bar through column " to build pile cap beam, " resistant bend and shear anchored reinforce steel bar " to strengthen column consolidation effect, and the method of " steel plate hoop " to build reinforcing bar connection of the foundation beam, etc. in the process of the consturction scheme research and implement, this paper synthetically elaborated the organizaton for project construction, put forward the construction technical measure of specific aim on the artificial pile, and pile cap beam, and underground adding layer and structure stabilization, and overall structure stabilization and so on. for this project, adopt reinforcing bar concrete to brace hole wall to ensure the safety of engineering in the artificial pile construction, use flexible connection catch to make the cage hoisting easier to simplify the construction process, use the method of earthwork statified symmetrical balance in the process of underground adding layer excavation
本文首先對于基礎托換與結構加固技術的目的和意義、國內外發展狀況進行了綜合闡述；其次對該項技術工程分類及適應范圍進行了理論上的分析研究；然後結合工程實例對該項技術進行了方案設計，對比幾種不同的托換方案和節點及構造設計，提出了「通筋穿柱法」做承臺梁， 「抗彎抗剪錨筋法」強化柱加固效果， 「鋼板箍法」做地基梁鋼筋連接點等多項技術；在施工方案的研究和實施過程中，對于工程施工組織進行綜合闡述，並就人工挖孔樁、承臺梁、地下加層及結構加固、整體結構穩定等專項施工方案提出有針對性的施工技術措施，人工挖孔樁施工採用鋼筋砼護壁確保挖孔樁的安全成型，使用柔性連接鉤進行鋼筋籠吊裝簡化施工工序；承臺梁施工採用梁主筋橫穿柱身化學膠錨固等；地下加層綜合施工技術採用土方分層對稱平衡開挖，分段挖土做筏基結構自穩等；最後對于該工程實施后的效果分析，說明該項綜合施工技術的可行性。 -
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體ansys6 . 0 ，採用線彈性方法，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，並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。
