Generally, the skew bridge ' s calculation theories can be divided into three types : the category 1 is the plank theories method, such as the finite difference method, the finite element method and the finite strip method, etc ; the category 2 is the beam theories, such as the grid beam theories, the general grid theories, the rigid cross - beam method, the elastically - supported continuous beam method and the bar system analytical method, etc ; the category 3 is the practical method, such as the g - m revising method, the grid - beam simple method and ghali form coefficient method, etc
目前關于斜梁橋的計算理論和方法概括起來，大致可以分為三類：第一類為板理論方法，如有限差分法、變分法、有限單元法、有限條法等；第二類為梁理論法，如格構梁理論、一般格構理論、剛性橫梁法、彈性支承連續法、桿件結構的分析方法；第三類為實用計演算法，荷載橫向分佈的計算方法如g ? m修正法、格構梁的簡易法、 ghali表格系數法等。 -
Fabrication of the box beam is divided into such parts as reinforcement, formwork, concreting, prestressing, moving and storing of beam, pipe grouting under pressure, end sealing of the beam, water - proof layer on the bridge surface system, protective coating etc. the paper makes description of effective box beam construction technology and workmanship which can be adopted in other projects, such technologies as : manufacturing and fixing of reinforcement, steel reinforcement fixing baseplate, web plate and top plate respectively and lifting the steel skeleton into form, requirements of design and manufacturing and way of utilization for dismantling - erection type formwork and hydraulic formwork, optimization of concrete ratio, concrete pouring process of two ends of beam in priority over the middle, in sequence of first baseplate followed by web plate and top plate at last, concrete pouring in inclined section and in horizontal layer, concrete vibration mainly by external vibrator in assistance with internal vibrator, methods and regulation for steam curing of concrete, dual controls over stress and strain to ensure quality of prestressing workmanship, construction method of effective beam moving by heavy - weight special moving facility, some regulations and key notes about construction of grouting under pressure, beam ends sealing, water - proof layer on the bridge surface system, protective coating
