1、摘要本设计是湖南省龙山至永顺二级公路初步设计,路段地处丘陵区,沿路地形起伏在400~600m之间,路线起止桩号从K4+000.000至K7+006,该公路的主要技术指标为路基宽度8.5m,双向双车道,无中央分隔带,设计车速60km/h。本次设计的是二级公路的初步设计,首先进行了地形图的研究,在熟悉地形图之后,查阅了当地相关的地形地质,水文气候条件,拟定了两条路线比选方案,在经过比较技术指标及经济指标后,最终选择最佳方案。在路线的平面设计之后,进行了纵横断组合设计、路基设计、路面设计。在路基路面设计完
2、成之后,路基设计专项中的挡土墙设计以及路基路面排水的设计。挡土墙采用的是重力式挡土墙,排水防护设计进行了边沟、排水沟以及截水沟的组合形式。然后进行了涵洞以及平面交叉设计,本路线需要构造两处涵洞,采用圆管涵形式,交叉口采用加铺转角式。最后对进行了工程的概预算,利用纵横概预算软件计算,概算金额为11439135元。关键词:湖南,龙山,永顺,二级公路,初步设计IABSTRACTThedesignofHunanprovinceLongshantoYongshuntworoadsectionsinthepre
