【正文】 使鋼軌產(chǎn)生撓曲附加力，與撓曲變形和扣件阻力的大小有關(guān)。伸縮附加力與梁的日溫度差和扣件阻力的大小有關(guān)。 橋上無(wú)縫線路橋上無(wú)縫線路設(shè)計(jì)主要包括[9~12]：(1)鋼軌的伸縮附加力的計(jì)算。把焊接軌條長(zhǎng)度延長(zhǎng)達(dá)整個(gè)區(qū)間或跨區(qū)間并與道岔焊聯(lián)成一體，這種超長(zhǎng)軌條的無(wú)縫線路稱為區(qū)間無(wú)縫線路或跨區(qū)間無(wú)縫線路。(3)線路大修縱斷面設(shè)計(jì)：線路大修縱斷面設(shè)計(jì)的目的是改善原有線路設(shè)備的技術(shù)狀態(tài)，本設(shè)計(jì)在既有路基面標(biāo)高、軌面標(biāo)高及既有道床厚度的基礎(chǔ)上，利用Excel對(duì)計(jì)算軌面標(biāo)高、設(shè)計(jì)軌面標(biāo)高、設(shè)計(jì)道床厚度等進(jìn)行計(jì)算，并繪制縱斷面設(shè)計(jì)改善圖[4]?！裕? 設(shè)計(jì)內(nèi)容本設(shè)計(jì)中采取的方法及步驟如下：(1)根據(jù)設(shè)計(jì)任務(wù)書(shū)給定的運(yùn)營(yíng)條件及線路測(cè)量資料，對(duì)既有線路平縱斷面進(jìn)行改善。 checking the track’s strength and stability, then designs the CWR on the roadbed, by calculating expansion forces and flexibility forces in the rails on the bridge, designing the CWR on a medium span steel bridge, and it draws the plan of long section of track layout of CWR. Finally the work of track renewal done a special study.Keywords: track renewal CWR track strength stability目 錄第1章 緒論 1 線路大修 1 概述 1 設(shè)計(jì)內(nèi)容 1 鐵路無(wú)縫線路 2 概述 2 路基上無(wú)縫線路 3 橋上無(wú)縫線路 3第2章 線路大修平面設(shè)計(jì) 4 概述 4 既有曲線漸伸線長(zhǎng)度計(jì)算 6 設(shè)計(jì)曲線漸伸線長(zhǎng)度計(jì)算 7 撥距計(jì)算 10第3章 線路大修縱斷面設(shè)計(jì) 17 縱斷面設(shè)計(jì)的特點(diǎn)及原則 17 設(shè)計(jì)特點(diǎn) 17 設(shè)計(jì)原則 17 縱斷面設(shè)計(jì)技術(shù)條件 17 縱斷面設(shè)計(jì)方法 18 縱斷面設(shè)計(jì)步驟 18 設(shè)計(jì)縱斷面 19 原始資料 20 設(shè)計(jì)數(shù)據(jù)及計(jì)算結(jié)果 22 設(shè)計(jì)縱斷面圖 24第4章 路基上無(wú)縫線路設(shè)計(jì) 26 無(wú)縫線路基本技術(shù)條件 26 無(wú)縫線路分類 26 無(wú)縫線路鋪設(shè)地段和位置 26 59 要求與規(guī)則 62 線路大修的周期性 62 影響因素 62 現(xiàn)行規(guī)定 63 如何確定大修周期 63參考文獻(xiàn) 66第1章 緒論 線路大修 概述鐵路線路是由路基、軌道和橋隧建筑物組成。關(guān)鍵詞：線路大修 無(wú)縫線路 軌道強(qiáng)度 穩(wěn)定性AbstractCWR is one hallmark of the railway modernization, it has some advantages such as smooth running, fortable and length of service life. With the increasing of driving speed, passenger capacity and cargo carrying capacity, and increasing of axial load, CWR has been a firstly chosentract construction of highspeed and heavyload track, so interregional CWR has been trend of rail track development in China. Line after longterm operation, line profile will change. Therefore, the existing profile have been investigated, under investigation, the line profile is to improve.This project improves the track’s plan and profile design of track renewal on the railway with the help of Auto CAD and Excel, moreover, it draws the plan of the railway’s profile improved design。本設(shè)計(jì)利用Auto CAD及Excel，對(duì)線路大修地段進(jìn)行
