【正文】 I 摘要 為了鞏固我們所學(xué)的知識(shí)，并在各方面得到更進(jìn)一步的提高，我們選擇了 蘇州至無(wú)錫某新建一級(jí)公路工程設(shè)計(jì) 作為畢業(yè)設(shè)計(jì)，這是在畢業(yè)之前對(duì)自身學(xué)習(xí)狀況的最后一次檢查。 我所選擇的設(shè)計(jì) 路 段 是 從 K0+000 至 K3+ 段 ，全長(zhǎng) 米 ，設(shè)計(jì)車速80km/h,路基寬度為 。 此次畢業(yè)設(shè)計(jì)主要包括的內(nèi)容如下： 路線設(shè)計(jì)：在已知平面圖的情況下，進(jìn)行縱斷面的設(shè)計(jì)，要求線路順暢、填挖平衡、經(jīng)濟(jì)合理。 路基設(shè)計(jì) ：包括各個(gè)樁號(hào)的填挖計(jì)算、填挖較大地段 的穩(wěn)定分析、整個(gè) 線路的土石調(diào)運(yùn)借配 等 。 路基、路面排水 工程； 高填挖地段的 防護(hù)工程 以及路基加固工程 ：這一部分相當(dāng)重要，對(duì)于路基排水，采用了邊溝、截水溝、急流槽等排水設(shè)施；對(duì)于路面排水，除了對(duì)路面進(jìn)行了路拱設(shè)計(jì)；對(duì)于特殊路段的防護(hù)和加固主要采用了骨架內(nèi)植草和擋土墻。 路面設(shè)計(jì)： 路基 在不同 干濕 狀態(tài)下， 設(shè)計(jì) 瀝青路面 要求經(jīng)濟(jì)合理，便于施工并滿足各設(shè)計(jì)規(guī)范要求。 關(guān)鍵詞 路線；路基路面；綜合設(shè)計(jì) II Abstract In order to consolidate our knowledge, and in all respects to be further improved, we chose LiaoNing province a new highway design as part of the graduation design, it is before graduation of their learning situation for a final check. In this design, our task is to design an secondary road. The road, which is m from K0+000 to K3+. The design speed is 80km/h and the wide of the subgrade is . Route design : the known ichnography, longitudinal section design, request line smooth, cut and fill balance, economic and reasonable. The roadbed design: including various pile excavation calculation, cut and fill larger sections of the stability analysis, the whole line of earthrock allocation by etc..The design of pavement, and this contents that the select of the construction about concrete and asphalt pavement in different case. 3 、 Subgrade, pavement drainage engineering。 high cut and fill area protection works and foundation reinforcement engineering: this part is very important, for the drainage of subgrade, the ditches, drainage ditches, chute, drainage facilities。 to pavement drainage, in addition to the pavement of road design。 in the special section of the reinforcement and protection by the framework of grass and earth retaining wall. 4 、 avement design: Subgrade under different wet and dry conditions, design of asphalt pavement requirements reasonable economy, convenient construction and meet the design requirement..
