設(shè)計(jì)計(jì)算書

摘要： 本設(shè)計(jì)上部結(jié)構(gòu)為鋼筋混凝土簡支梁橋，標(biāo)準(zhǔn)跨徑為14米×3，橋面凈空：凈—8+2×1.0米，采用重力式橋墩和橋臺(tái)。橋梁全長為42m，橋面總寬10m，橋面縱坡為0.3%，橋梁中心處橋面設(shè)計(jì)高程2.00米，橫坡為1.5%；橋垮軸線為直線，設(shè)計(jì)荷載標(biāo)準(zhǔn)為：公路-Ⅱ級(jí)，人群荷載3 kN/m。本文主要闡述了該橋設(shè)計(jì)和計(jì)算過程，首先對(duì)主橋進(jìn)行總體結(jié)構(gòu)設(shè)計(jì)，然后對(duì)上部結(jié)構(gòu)進(jìn)行內(nèi)力、配筋計(jì)算，再進(jìn)行強(qiáng)度，應(yīng)力及變形驗(yàn)算，最后進(jìn)行下部結(jié)構(gòu)設(shè)計(jì)和結(jié)構(gòu)驗(yàn)算。同時(shí)，也給出了各部分內(nèi)容相關(guān)的表格與圖紙。通過這次設(shè)計(jì)不但了解設(shè)計(jì)橋梁的各個(gè)步驟，而且也能熟練的運(yùn)用AUTOCAD進(jìn)行制圖。

ABSTRACT： The design for the upper structure of reinforced concrete beam bridge, standard span for 14 meters x 3, bridge deck headroom: net - 8 + 2 x 1.0 meters, adopt the piers and gravity type abutment. Bridge deck 42m, stretches for total wide ZongPo 0.3%, 10m bridge deck, deck design elevation 2.00 at the center of the slope for rice, 1.5%; Bridge collapse, design load for linear axis for: highway - Ⅱ standard, the crowd load level 3 kN/m. This paper mainly expounds the bridge design and calculation process, first makes an overall structure design of bridge, then to the upper structure force, reinforcement calculation, again, stress and deformation strength, then check the structure design and structure checking. At the same time, also gives the relevant sections of the form and drawings. This design not only understand each step of designing the bridge, but also can skilled use AUTOCAD for drawing.
Keywords: cast-in-situ concrete simply-supported t-shaped bridge abutment gravity type abutment gravity type structure design checking intensity
