【正文】 常保養(yǎng)和臨時(shí)補(bǔ)修。線路維修工作，必須掌握線路設(shè)備技術(shù)狀態(tài)變化規(guī)律，貫徹“預(yù)防為主，防治結(jié)合，修養(yǎng)并重” 的原則。線路在長期的運(yùn)行過程中，由于輪軌相互作用而逐漸磨耗，使線路產(chǎn)生不均勻變形并不斷積累，導(dǎo)致線路附加力作用加大，鋼軌及其軌下基礎(chǔ)負(fù)擔(dān)日益增大，承載能力不斷降低。 Graphic design。s current railway line maintenance rules and reconstruction technique norms and engineering drawings standard, conform to the state standards.Keywords: Heavy repair。所有這些內(nèi)容都參照我國現(xiàn)行的鐵路線路維修規(guī)則和改擴(kuò)建工程技術(shù)規(guī)范及工程制圖規(guī)范書寫的，符合國家標(biāo)準(zhǔn)。，補(bǔ)充道碴，改善道床斷面。、鋼軌伸縮調(diào)節(jié)器以及不合規(guī)定的護(hù)輪軌，更換絕緣接頭及鋼軌連續(xù)線。一般情況下，線路大修周期取決于鋼軌傷損發(fā)展情況，是以全面更換鋼軌為主要標(biāo)志，故常稱換軌大修。蘭州交通大學(xué)博文學(xué)院畢業(yè)設(shè)計(jì)(論文)摘 要本設(shè)計(jì)是運(yùn)用所學(xué)軌道基本理論，知識(shí)和技能，進(jìn)行工程設(shè)計(jì)的綜合訓(xùn)練，是綜合素質(zhì)和工程實(shí)踐能力的重要體現(xiàn)，是每個(gè)學(xué)生都必須經(jīng)過的作為一個(gè)鐵道工程技術(shù)人員所必須的訓(xùn)練，有助于到工作崗位的過渡。線路設(shè)備大修的基本任務(wù)是：根據(jù)運(yùn)輸需要及線路設(shè)備的損耗規(guī)律，有周期、有計(jì)劃地對損耗部分進(jìn)行更新和修理，恢復(fù)與增強(qiáng)軌道承受能力，延長設(shè)備的設(shè)備壽命。線路換軌大修主要工作內(nèi)容：。，補(bǔ)足軌枕配置根數(shù)，修理傷損軌枕。，應(yīng)同時(shí)成組更換新道岔和新岔枕。因涉及到的內(nèi)容很多，所以利用電子表格 EXCEL 來進(jìn)行計(jì)算，以達(dá)到更快、更準(zhǔn)、更有效率的目的；其他內(nèi)容也做到有的放矢。關(guān)鍵詞：大修；換軌；平面設(shè)計(jì)；縱斷面設(shè)計(jì)蘭州交通大學(xué)博文學(xué)院畢業(yè)設(shè)計(jì)(論文)AbstractThe graduation design as the last link of teaching plan, is the basic theory, use orbit knowledge and skills, project design, the prehensive training is prehensive quality and engineering practice ability, is the important embodiment of each student must pass a railroad engineers must training, helps to jobs.The basic task of the line equipment repair is: according to the transportation needs and lines of law, have cycle, planful part of loss, updated and repair recovery and enhance rail bear ability, prolong the service life of equipment equipment. Normally, line overhaul period depends on the development situation, based on prehensive replacement for major rail, in particular said.Lines in overhaul main job content: to the design of the correction to improve line longitudinal peace. overall change new rail and accessories, trak controller and illegal armor wheel and rail, insulation joint replacement continuous line. failure sleeper and buckles, plemental sleeper, repair of configuration injury sleeper. thoroughly clear sieve solid, added ballastless track, improve section., should also group overhaul and replacement of new nechanics new rail. strengthen equipment installation orbit.Because the content involves many, so use spreadsheet EXCEL to pute, faster and more accurate in order to achieve the goal, more efficient, Other contents and try to use puter colleg and use software. All these content to China39。 Replacement track。 Longitudinal design蘭州交通大學(xué)博文學(xué)院畢業(yè)設(shè)計(jì)(論文)I目 錄第一章 緒論 .........................................................................................................................1第一節(jié) 線路大修內(nèi)容 ..................................................................................................1一、線路大修概述 ................................................................................................1二、線路大修主要內(nèi)容 ........................................................................................1第二節(jié) 設(shè)計(jì)線路中主要采用的技術(shù)指標(biāo) ..................................................................2一、線路技術(shù)標(biāo)準(zhǔn) ................................................................................................2二、軌道標(biāo)準(zhǔn) ........................................................................................................2第二章 大修勘測及既有線路資料的調(diào)查 .........................................................................4第一節(jié) 既有線大修勘測的基本原理和施測方法 ......................................................4一、既有線大修勘測的基本原理 ........................................................................4二、施測方法 ........................................................................................................5第二節(jié) 線路大修勘測及既有線路資料的調(diào)查 ..........................................................6一、寶成線概況 ....................................................................................................6二、寶成線勘測 ....................................................................................................6第三章 平面大修設(shè)計(jì) .......................................................................................................10第一節(jié) 偏角法計(jì)算曲線撥距 ....................................................................................10一、漸伸線原理 ..................................................................................................10二、用漸伸線原理計(jì)算既有曲線的撥距 ..........................................................13第二節(jié) 繩正法計(jì)算曲線撥距 ....................................................................................16一、繩正法原理 ..................................................................................................16二、用繩正法原理計(jì)算既有曲線的撥距 ..........................................................19第四章 線路大修縱斷面設(shè)計(jì) ...........................................................................................25第一節(jié) 縱斷面設(shè)計(jì)的特點(diǎn)及原則 ............................................................................25一、設(shè)計(jì)特點(diǎn) ......................................................................................................25二、設(shè)計(jì)原則 ......................................................................................................25第二節(jié) 縱斷面設(shè)計(jì)的基本原理 ................................................................................26一、線路坡度 ......................................................................................................26二、坡段長度 ......................................................................................................27三、坡段連接 ......................................................................................................28蘭州交通大學(xué)博文學(xué)院畢業(yè)設(shè)計(jì)(論文)II第三節(jié) 縱斷面設(shè)計(jì)的方法和步驟 ............................................................................31一、縱斷面設(shè)計(jì)圖 ..............................................................................................31二、計(jì)算軌面標(biāo)高 ..............................................................................................33三、設(shè)計(jì)坡度與設(shè)計(jì)軌面線 ..............................................................................33四、計(jì)算起道高度 ..............................................................................................34五、計(jì)算設(shè)計(jì)道床厚度 .......................................
