1、某新建二級公路設(shè)計專業(yè):道路橋梁工程技術(shù)題目:某新建二級公路設(shè)計起始樁號:K0+000~K2+274.5緒論為了鞏固我們所學(xué)的知識,并在各方面得到更進(jìn)一步的提高,我們選擇了重慶某地區(qū)新建二級公路設(shè)計作為畢業(yè)設(shè)計,這是在畢業(yè)之前對自身學(xué)習(xí)狀況的最后一次檢查。我所選擇的設(shè)計路段是從K0+000至K2+274.5段,全長2274.5米,設(shè)計車速60km/h,路基寬度為10m。此次畢業(yè)設(shè)計主要包括的內(nèi)容如下:1、路線設(shè)計:在已知平面圖的情況下,進(jìn)行縱斷面的設(shè)計,要求線路順暢、填挖平衡、經(jīng)濟(jì)合理。2、路基設(shè)計:包括各個樁號的填挖計算、填挖較大地段的穩(wěn)定分析、整個線路的土石調(diào)運借配等。3、路面設(shè)計:
2、路基在不同干濕狀態(tài)下,所設(shè)計的瀝青路面和水泥混凝土路面方案的比選,要求經(jīng)濟(jì)合理,便于施工并滿足各設(shè)計規(guī)范要求。4、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,對于路基排水,采用了邊溝、截水溝、急流槽等排水設(shè)施;對于路面排水,除了對路面進(jìn)行了路拱設(shè)計,還進(jìn)行中央分隔帶的排水設(shè)計;對于特殊路段的防護(hù)和加固主要采用了骨架內(nèi)植草和擋土墻。5、橋涵設(shè)計:包括橋梁和涵洞的形式、尺寸的設(shè)計。目錄1路線設(shè)計·······················································11.1線形設(shè)計一般原則·················
