Abstract：This design for 338 broad line of Changzhou segment of a new road integrated design. According to the given of traffic and service level and properties, to determine this highway rating for the level, on this basis, according to the highway the requirement of the specifications, set a four-lane highway central belt, through the analysis of natural conditions and along the main technical indexes, The three schemes for possible than the election, determine the most reasonable design scheme, then the optimal scheme for the detailed design, The main contents include: line plane curve design, vertical curve design, roadbed design and culvert design this highway design speed for 60km/h, line length 2534.870 m, width for roadbed 23m, the central belt for the width of the 2m, there are three across for plane curve, three vertical curve, the two tunnels.
Keywords: traffic, level of roads, natural conditions and technical standard, the subgrade pavement, flat curve, vertical curve, culverts 食品安全演讲稿
