In the longitudinal section design lights a candle the putation vertical curve again each kind of essential factor, the longitudinal section design designs the highway design each putation station number ground elevation and the design elevation, obtains the putation course pile roadbed to fill in digs the altitude, then the putation obtains the roadbed cubic meter of earth and stone quantity, the filling in roadbed cubic meter of earth and stone meter. The cross section design has determined road39。s topic design research, is after having pleted four year university core curriculum as well as special course carries on, is studies the knowledge to a university four year institute a big examination and the synthesis utilization. This design divides into several parts to carry on, including in highway design each kinds both basic and the very important link, for example the plane design, the longitudinal section design, the cross section design, the roadbed pavement design, keep off protection engineering design and so on.

A prehensive design which this graduation project39。s determination uses is on the paper the route selection siting, the highway route finally determines after the topographic diagram, to road plane design39。s road pavement bed as well as each kind of facility arrangement position. The grade location had determined the roadbed cross fall as well as the embankment cut roadbed stability of slope processing, also has carried on the design to the roadbed and the road surface waterproof draining water design. What kept off the protection engineering design to carry on was the gravity bulkhead design, the road surface design has carried on two type pavement designs successively, namely rigid pavement and flexible pavement design. This design pleted may let the university graduates have an achievement road engineer the necessary basic quality and the basic skill, in the design uses puteraided design this new technology, the design final achievement to give in the design the various part of content related form and the blueprint.Key words：Arterial road； Plane design； Longitudinal section design；Cross section design；Draining water；Bulkhead； Blueprint目 次摘 要 IAbstract II1 平面設計 11．1 角度及相關距離計算 11．1．1 交點距離計算 11．1．2 導線方位角計算 21．1．3 導線間偏角計算 21．1．4 曲線要素計算 21．1．5 JD1處緩和曲線里程樁計算 31．1．6 JD2處緩和曲線里程樁計算 42 縱
