1、某新建二級(jí)公路設(shè)計(jì)專業(yè)：道路橋梁工程技術(shù)題目：某新建二級(jí)公路設(shè)計(jì)起始樁號(hào)：K0+000～K2+274.5緒論為了鞏固我們所學(xué)的知識(shí)，并在各方面得到更進(jìn)一步的提高，我們選擇了重慶某地區(qū)新建二級(jí)公路設(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K2+274.5段，全長(zhǎng)2274.5米，設(shè)計(jì)車速60km/h,路基寬度為10m。此次畢業(yè)設(shè)計(jì)主要包括的內(nèi)容如下：1、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。2、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。3、路面設(shè)計(jì)：
2、路基在不同干濕狀態(tài)下，所設(shè)計(jì)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(jì)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(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)，還進(jìn)行中央分隔帶的排水設(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。5、橋涵設(shè)計(jì)：包括橋梁和涵洞的形式、尺寸的設(shè)計(jì)。目錄1路線設(shè)計(jì)·······················································11.1線形設(shè)計(jì)一般原則·················
