1、摘要鐵路是現(xiàn)代文明的一項巨大工業(yè)成就，在國民經(jīng)濟的發(fā)展過程中發(fā)揮著不可或缺的作用，因此在本次鐵路選線設(shè)計當中，充分結(jié)合當?shù)氐匦蔚膶嶋H條件，力求作到行車安全平順、節(jié)約資金、布置合理、線形美觀。本篇為Ⅲ級鐵路東南村—九龍江段選線設(shè)計。此地區(qū)地形屬于山嶺重丘，路段全長4630m。設(shè)計內(nèi)容主要是依據(jù)《鐵路線路設(shè)計規(guī)范》、《鐵路選線設(shè)計》和《軌道結(jié)構(gòu)》等文獻進行平面線形設(shè)計、縱斷面設(shè)計、橫斷面設(shè)計、邊坡穩(wěn)定性驗算、擋土墻設(shè)計以及軌道結(jié)構(gòu)設(shè)計。平面線形設(shè)計主要是利用緯地軟件進行紙上定線、平曲線要素確定；縱斷面設(shè)計包括地面高程、設(shè)計高程、坡段

2、設(shè)計和豎曲線要素；橫斷面設(shè)計是根據(jù)地質(zhì)條件及《鐵路路基支檔物設(shè)計規(guī)范》，繪制出每樁橫斷面，同時對路基邊坡穩(wěn)定性分析，確定臨界高度，加上擋土墻。本文對軌道結(jié)構(gòu)的鋼軌、軌枕、道床以及曲線軌道的超高、加寬分別進行了設(shè)計，最后根據(jù)運營條件對軌道強度進行驗算。本設(shè)計在制圖方面嚴格按照中華人民共和國國家標準《道路工程制圖標準》進行，采用緯地CAD制圖，理正巖土對土坡和擋土墻進行驗算。關(guān)鍵詞：鐵路選線設(shè)計縱斷面橫斷面擋土墻邊坡穩(wěn)定性軌道結(jié)構(gòu)ABSTRACTAsanimportantpattenofthetransportation,railw
