【正文】 黑龍江科技學院交通土建畢業(yè)設計 摘要 1 摘 要 本設計是吉林省舒蘭市鳳凰鄉(xiāng)至東小鄉(xiāng)段一級公路的設計，本設計中設計車速為100km/h，雙向四車道。 本設計是在對交通量進行分析，查找相應的技術規(guī)范的基礎上，確定出公路的技術等級以及設計需要的各種參數(shù)，最終確定采用一級公路的技術指標進行設計。結合周圍的地形情況進行了平面線形設計，平面線形中有三個轉角?？v斷面的設計中有三個豎曲線，滿足平縱線形組合設計中的各種要求。在橫斷面的設計中，確定了橫斷面組成及各種要素后，繪制出橫斷面圖。本設計中路面設計采用瀝青路面進行設計，主要包括結構層的擬定和設計層厚度計算。 擋土墻設計主要是在擬定結構尺寸后進行各種強度的驗算。設計中結合地形及周邊環(huán)境條件，通過兩條線路方案的比選，最終確定最佳方案。 關鍵詞：一級公路；縱斷面；橫斷面；瀝青路面；擋土墻 1 Abstract This design is a secondary road design from fenghuang to dongxiao. The design speed is100km/h and the road have four lanes. The parameters which are needed in the design are defined by analyzing the traffic and searching the corresponding technical specification. Finally the XXXXX road’s technical specification is designed. Based on the surrounding terrain, the alignment of the highway is designed, which has three corners. There are three vertical curves in the design of vertical alignment, which all meet the design requirement of the linear bination. In the cross section design, the cross section diagrams are drawn after determining the position and cross section elements. The design of the asphalt pavement mainly contains the selection of the structure layer and the calculation of the layer thickness. The intension of the structure is checked after the selection of the dimensions of the structure in the culvert design. The design is bined with the terrain and surrounding environment conditions, and through the parison of two line programs, the best solution is ultimately determined.
