【摘要】：近年來,鋼桁梁橋在我國的鐵路、公路及城市人行天橋中得到廣泛運用,同時,鋼桁梁橋日趨朝著設(shè)計更新穎、造型更美觀、跨度更大、結(jié)構(gòu)更復雜的方向發(fā)展,鋼桁梁橋可視化已成為一個重要的研究課題。本文主要研究內(nèi)容包括以下幾個方面:(1)查閱國內(nèi)外關(guān)于鋼桁梁橋可視化的資料,了解鋼桁梁橋可視化的現(xiàn)狀;學習計算機圖形學、參數(shù)化建模及橋梁三維可視化等理論知識;分析鋼桁梁橋桿件工程圖紙,考慮鋼桁梁橋桿件工程圖紙的復雜性和鋼結(jié)構(gòu)自身的特點,制定本文研究的技術(shù)路線。(2)采用VC++程序開發(fā)語言,結(jié)合ObjectARX 2007工具包開發(fā)ARX程序,創(chuàng)建各類接口(繪圖環(huán)境設(shè)置、基本繪圖、標注),設(shè)置圖形屬性和文字屬性(圖層、文字樣式、標注樣式、顏色、線寬、線型等),繪制各種基本圖形(直線、圓、矩形、多段線),實現(xiàn)鋼桁梁橋工程圖自動繪制和三維建模功能。(3)采用VC++語言設(shè)計操作Excel 2007的類對象,實現(xiàn)創(chuàng)建新表、寫入數(shù)據(jù)、讀取數(shù)據(jù)、合并單元格、存儲表等功能�；诖祟悓ο�,創(chuàng)建各類鋼桁梁橋桿件材料表的接口,在繪制鋼桁梁橋桿件的同時自動生成材料表,將桿件部分尺寸數(shù)據(jù)和屬性信息自動存儲到Excel表單中。(4)分析鋼桁梁橋的數(shù)據(jù)結(jié)構(gòu),用Access數(shù)據(jù)庫設(shè)計鋼桁梁橋整體信息表和桿件信息表兩個表對象。采用ADO技術(shù)將鋼桁梁橋數(shù)據(jù)庫鏈接到程序中,設(shè)計數(shù)據(jù)項的增、刪、改功能,實現(xiàn)對鋼桁梁橋數(shù)據(jù)庫的維護。(5)基于Windows消息機制和ObjectARX 2007開發(fā)工具包,設(shè)計對話框、菜單、可�？看绑w、AutoCAD命令,實現(xiàn)良好的軟件人機互操作。本文研究鋼桁梁橋可視化技術(shù)與方法,以趙寨潁河雙線特大橋施工圖為例,實現(xiàn)了鋼桁梁橋桿件的參數(shù)化繪圖、三維建模及信息管理,大大提高了繪圖及信息管理效率,總結(jié)了一套基于AutoCAD的鋼桁梁橋可視化技術(shù)和方法,對于鋼桁梁橋的設(shè)計與建設(shè)具有一定的意義。
[Abstract]:In recent years, steel truss bridges have been widely used in railway, highway and urban pedestrian overpasses in our country. At the same time, steel truss bridges are developing towards the direction of more novel design, more beautiful shape, larger span and more complicated structure. Visualization of steel truss bridges has become an important research topic. The main contents of this paper include the following aspects: 1) to consult the visualization data of steel truss bridges at home and abroad, to understand the present situation of visualization of steel truss bridges, to study computer graphics, Theoretical knowledge of parametric modeling and 3D visualization of bridges, analysis of the engineering drawings of steel truss bridges, considering the complexity of the engineering drawings of steel truss bridges and the characteristics of steel structures, Using VC programming language and combining with ObjectARX 2007 Toolkit to develop ARX program, to create all kinds of interfaces (setting up drawing environment, basic drawing, marking, setting up graphic attribute and text property (layer, text style). Label style, color, line width, line shape and so on, draw all kinds of basic graphics (straight line, circle, rectangle, multi-section line, realize automatic drawing of steel truss bridge engineering drawing and 3D modeling function.) use VC language to design and operate the class object of Excel 2007. Realize the function of creating new table, writing data, reading data, merging cell, storing table and so on. Based on this kind of object, the interface of all kinds of steel truss bridge member material table is created, and the material table is generated automatically while drawing steel truss bridge member. The data structure of steel truss bridge is analyzed by automatically storing part dimension data and attribute information in Excel form. The whole information table and the member information table of steel truss bridge are designed by using Access database. The database of steel truss bridge is linked to the program by ADO technology, and the function of adding, deleting and changing the design data item is obtained. Realizing the maintenance of steel truss bridge database. 5) based on Windows message mechanism and ObjectARX 2007 development kit, designing dialog box, menu, docking form and AutoCAD command. The visualization technology and method of steel truss bridge are studied in this paper. Taking the construction drawing of Zhaozhai Yinghe double-line large bridge as an example, the parametric drawing, three-dimensional modeling and information management of steel truss bridge members are realized. The efficiency of drawing and information management is greatly improved, and a set of visualization techniques and methods of steel truss bridge based on AutoCAD are summarized, which is of certain significance for the design and construction of steel truss bridge.
