关键词：路线，路基,路面,涵洞，平面交叉，概算

ABSTRACT

Data that this design according to give to settle to complition, complete the Threexin

forest of Mulin to lianhe highway station segment (1) first design station segment (2) the relevant technique index sign for kind, geography for second class highway route, from this design learning a lot of knowledge concerning highways, passing analysis primitive dataing, according to the road's segment, characteristics of term nature, such as, ground thing, and hydrology etc., Basis highway engineering technique standard , highway route designing the normal waiting the transport, and complete to design under the help that the teacher's leading is with the classmate of constitute the circumstance,

The design inside of stage first steps include: Route design,The paper up settles the

lines( mountain range area, or more mountain range line),Draw the route plane chart, Proceed route vertical section of design;Roadbed design, Complete two kilometer cross sections are with the roadbed the calculation of square ground and roadbed drain the design;Road design, Cement concrete road design;Small bridge culvert design, Complete the design of a culvert;The route crosses the design, Complete a route flat surface to cross; Design budgetary estimate establishment: Completes the entire line todesign the road section the preliminary design budgetary estimate;The application calculator draws the engineering diagram, Complete under the teacher's leading request.

we compute the route even, vertical , horizontal main factor, designed the flat surface

to designtheroadbed,roadthesizefor, small bridge culvert, fromhere,successfully completed Qingnian to Qianjin of the Beicui highway in section two stages preliminary designs.

Key words: Route, roadbed, road, culvert，Route cross，Budgetary estimate
