【正文】 大學(xué)畢業(yè)設(shè)計（論文） I 摘要 隨著社會經(jīng)濟的發(fā)展，公路起著越來越重要的作用。本文主要講述了公路設(shè)計中的一個完整的過程。本設(shè)計主要分兩個階段：初步設(shè)計階段和詳細設(shè)計階段。 首先，討論道路修建的可行性，從地形，地質(zhì)，氣象，水文條件等自然因素和交通量的增長情況來論述該公路修建的可行性與必要性，為道路修建進行理論研究。 其次，本著合理利用當(dāng)?shù)刭Y源，綜合考慮地形，地質(zhì)，水文氣象條件等自然因素和當(dāng)前交通量以及交通量增長情況來確定公路等級，并根據(jù)公路等級來確定道路設(shè)計中的技術(shù)指標(biāo)。 最后，為了作到路線方案的最優(yōu)，選擇兩條方案分別進行初步設(shè)計。根據(jù)一定的技術(shù)指標(biāo)來進行方案的比選，選擇合理的路線方案來進行詳細設(shè)計。 關(guān)鍵詞 公路 設(shè)計 路基設(shè)計 路面設(shè)計 大學(xué)畢業(yè)設(shè)計（論文） II Abstract As the development with the social economy, the highway plays more and more important role. This design contains the whole stage in the designing course . First of all, discussing the feasibility building in road, at topograph, and the growth situations of volume of traffic e and expoud the fact this feasibility and necessity who highway build meteorological hydrology terms, etc. natural factorses geology. Build the theoretical hydrology research for the road. Secondly, in line with utilizing local resources rationally, Consider and at present and volume of traffic increase traffic situation e and determine highway grade topographies, geologies, hydrometorological termeseses natural factors. At last, e and determine road the technical indicators of design according to highway grade. Moreover, for acplishing scheme optimum route, choose two schemes to be designed tentatively respectively. Come and carry on to then selecting, choose rational route scheme design in detail scheme according to certain technical indicator.
