1、市太平嶺至中石樁子公路施工圖設(shè)計(jì)摘要此次設(shè)計(jì)的容是從市太平嶺到中石樁子村(K0+000-K2+319.810)的公路，該公路為集散公路，考慮到設(shè)計(jì)交通量、該公路所在地區(qū)的經(jīng)濟(jì)條件等因素，確定公路等級(jí)為二級(jí)。這次設(shè)計(jì)的容主要有平面線型設(shè)計(jì)（確定交點(diǎn)轉(zhuǎn)角,交點(diǎn)處圓曲線半徑和前后緩和曲線長(zhǎng)度以及計(jì)算移值、切線增長(zhǎng)值、緩和曲線角外距等），縱斷面設(shè)計(jì)（先根據(jù)縱斷面地面線拉坡，然后再設(shè)計(jì)豎曲線），橫斷面設(shè)計(jì)（主要有行車道、硬路肩、土路肩、填方邊坡、排水溝、邊溝、挖方邊坡等的設(shè)計(jì)，另外還要根據(jù)平面圓曲線半徑等來確定是否需要設(shè)置超高和加寬），路面結(jié)構(gòu)設(shè)計(jì)（先根據(jù)交通量組成確定路面設(shè)
2、計(jì)彎沉值，然后初步擬定結(jié)構(gòu)層類型和厚度，再通過將多層體系轉(zhuǎn)化為當(dāng)量三層體系確定未知結(jié)構(gòu)層厚度，最后驗(yàn)算各結(jié)構(gòu)層層底拉應(yīng)力），涵洞設(shè)計(jì)（該設(shè)計(jì)中，涵洞與路線正交且為圓管涵）。關(guān)鍵詞：平面線型，縱斷面，橫斷面，路面，涵洞HighwayConstructionDesignFromTaipinglingToZhongshizhuangziInTheCityOfDunhuaAbstractThecontentofthedesignisaroadfromTaipinglingtoZhongshizhuangziinthecityofDnhua(K0+000-K2+319.810
