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A標段一級公路設(shè)計摘要此次畢業(yè)設(shè)計是對寧安市石巖鎮(zhèn)至江東林場段重丘陵地區(qū)的一級公路的方案設(shè)計，首先從選線、布線開始，依次進行平面設(shè)計、縱斷面設(shè)計、橫斷面的設(shè)計，通過平縱橫結(jié)合和交通量以及設(shè)計時速，得出路線的超高，從建設(shè)的經(jīng)濟性和合理性方面進行方案的比選，最后根據(jù)實際情況選出最合適的方案，盡量采取少挖填，減少工程量。然后進行公路擋土墻設(shè)計、路基路面設(shè)計。擋土墻主要進行主動土壓力驗算、穩(wěn)定性驗算（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算，從而確保擋土墻安全穩(wěn)定；路基路面
2、設(shè)計主要對道路橫斷面的設(shè)計以及路面結(jié)構(gòu)層的設(shè)計和計算，橫斷面設(shè)計主要根據(jù)交通量和時速以及邊坡坡度，同時保證排水的前提下進行設(shè)計；結(jié)構(gòu)層設(shè)計是根據(jù)自然區(qū)劃選擇路面材料，同時也要對路面的強度、剛度和穩(wěn)定性進行驗算，以確保一級公路，在結(jié)構(gòu)層方面的穩(wěn)定性，該設(shè)計同時也給出了平縱橫設(shè)計相關(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；一級公路；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
