介绍: 为了巩固我们所学的知识,并在各方面得到更进一步的提高,我们选择了重庆某地区新建二级公路设计作为毕业设计,这是在毕业之前对自身学习状况的最后一次检查。 我所选择的设计路段是从K0+000至K2+274.5段,全长2274.5米,设计车速60km/h,路基宽度为10m。 此次毕业设计主要包括的内容如下: 1、路线设计:在已知平面图的情况下,进行纵断面的设计,要求线路顺畅、填挖 平衡、经济合理。 2、路基设计:包括各个桩号的填挖计算、填挖较大地段的稳定分析、整个线路的土石调运借配等。 3、路面设计:路基在不同干湿状态下,所设计的沥青路面和水泥混凝土路面方案的比选,要求经济合理,便于施工并满足各设计规范要求。 4、路基、路面排水工程;高填挖地段的防护工程以及路基加固工程:这一部分相当重要,对于路基排水,采用了边沟、截水沟、急流槽等排水设施;对于路面排水,除了对路面进行了路拱设计,还进行中央分隔带的排水设计;对于特殊路段的防护和加固主要采用了骨架内植草和挡土墙。 桥涵设计:包括桥梁和涵洞的形式、尺寸的设计。 目 录 1路线设计·······················································1 1.1线形设计一般原则············································1 1.2平面线形要素的组合类型······································1 1.3平面设计方法················································2 1.4平曲线设计··················································2 1.5纵断面设计··················································4 1.6横断面设计··················································5 2路基路面设计····················································7 2.1一般路基设计················································7 2.2软基处理····················································8 2.3路基防护···················································9 2.4支挡结构设计···············································9 2.5路面结构设计···············································10 2.6路基土石方数量计算及调配···································11 3路基路面排水设计··············································14 3.1路基排水设计···············································14 3.2路面排水设计···············································14 4涵洞基本构造··················································14 4.1圆管涵·····················································14 4.2盖板涵·····················································15 5设计计算表··················································· 6参考文献······················································ 7结束语························································
