1、哈爾濱理工大學(xué)學(xué)士學(xué)位論文寧安市石巖鎮(zhèn)至江東林場(chǎng)A標(biāo)段一級(jí)公路設(shè)計(jì)摘要此次畢業(yè)設(shè)計(jì)是對(duì)寧安市石巖鎮(zhèn)至江東林場(chǎng)段重丘陵地區(qū)的一級(jí)公路的方案設(shè)計(jì)，首先從選線、布線開(kāi)始，依次進(jìn)行平面設(shè)計(jì)、縱斷面設(shè)計(jì)、橫斷面的設(shè)計(jì)，通過(guò)平縱橫結(jié)合和交通量以及設(shè)計(jì)時(shí)速，得出路線的超高，從建設(shè)的經(jīng)濟(jì)性和合理性方面進(jìn)行方案的比選，最后根據(jù)實(shí)際情況選出最合適的方案，盡量采取少挖填，減少工程量。然后進(jìn)行公路擋土墻設(shè)計(jì)、路基路面設(shè)計(jì)。擋土墻主要進(jìn)行主動(dòng)土壓力驗(yàn)算、穩(wěn)定性驗(yàn)算（包括抗傾覆穩(wěn)定性和抗滑移穩(wěn)定性）以及地基承載力的驗(yàn)算，從而確保擋土墻安全穩(wěn)定；路基路面
2、設(shè)計(jì)主要對(duì)道路橫斷面的設(shè)計(jì)以及路面結(jié)構(gòu)層的設(shè)計(jì)和計(jì)算，橫斷面設(shè)計(jì)主要根據(jù)交通量和時(shí)速以及邊坡坡度，同時(shí)保證排水的前提下進(jìn)行設(shè)計(jì)；結(jié)構(gòu)層設(shè)計(jì)是根據(jù)自然區(qū)劃選擇路面材料，同時(shí)也要對(duì)路面的強(qiáng)度、剛度和穩(wěn)定性進(jìn)行驗(yàn)算，以確保一級(jí)公路，在結(jié)構(gòu)層方面的穩(wěn)定性，該設(shè)計(jì)同時(shí)也給出了平縱橫設(shè)計(jì)相關(guān)的表格跟圖紙以及挖填的土石方調(diào)配表和路線的三維模擬圖等內(nèi)容。關(guān)鍵詞公路設(shè)計(jì)；一級(jí)公路；仰斜式擋土墻；瀝青路面-I-哈爾濱理工大學(xué)學(xué)士學(xué)位論文NinganrocktowntojiangdongforestbidAlevelofhighwaydesign
