北滨路道路工程-管涵保护结构施工图计算书

PAGE1北滨路道路工程管涵保护结构施工图计算书一、设计资料管涵保护采用门型框架结构形式，结构尺寸如下图示。计算荷载选择其中最不利荷载进行验算。断面尺寸最大覆土厚度30m。车辆荷载：城-B级，结构重要性系数：1.1，材料：框架结构：C40，钢筋：HRB400，钢筋布置详施工图。土的容重：20kN/m3钢筋混凝土容重：26kN/m31.1荷载取值计算:恒载竖向按覆土的自重考虑：q=B×H×(土厚)×γ=1m×30m×20kN/m3=600kN/m恒载侧向按主动土压力计算：q1=K0×γ×H×bK0为土的侧压力系数，K0=tan(45-Φ/2),按Φ=30考虑;K0=0.33；q1=0.33×20kN/m3×30m×1m=198kN/mq2=0.33×20kN/m3×33.8m×1m=224kN/m汽车荷载汽车荷载等效土层厚度：汽车轮着地宽度0.6m，由《公路桥涵设计通用规范》(JTGD60—2015)第4.3.4条规定，按30°角向下分布。一个汽车轮横向分布宽：0.6/2（半个车轮）+Htan30°=0.3m+30m×√3/3=17.6m故车轮压力扩散线相重叠，应按如下计算横向分布宽度(m为车道数):a=(0.6/2+Htan30°)×2+1.8×m+1.3×(m-1)=17.6×2+1.8×3+1.3×(3-1)=43.2m一个汽车轮纵向分布宽：0.2/2（半个车轮）+Htan30°=0.1m+30m×√3/3=17.4m按如下计算纵向分布宽度：b=(0.2/2+Htan30°)×2+18=17.4×2+18=52.8m总重：G=3×(60+140+140+200+160)=2100kN等效土层厚度：h=1*G/(a×b×γ)=0.05m活载竖向：q=B×h(土厚)×γ=1m×0.05m×20kN/m3=1.0kN/m活载侧向：q1=K0×γ×h×B=0.33×20kN/m3×0.05m×1m=0.33kN/m二、主要设计依据1、《公路桥涵设计通用规范》（JTGD60-2015）2、《公路钢筋混凝土及预应力混凝土桥涵设计规范》（JTGD62-2004）3、《城市桥梁设计规范》（GJJ11－2011）4、《公路桥涵地基与基础设计规范》（JTGD63-2007）三、框架结构计算3.1模型建立采用“MiasCivil”软件进行建模计算，框架按钢筋混凝土构件进行设计，按受弯构件进行计算，计算模型如下：计算模型图3.2框架计算结果3.2.1抗弯验算单元位置最大/最小组合
