【文章內(nèi)容簡(jiǎn)介】 by various sorts of tourist proprietors, the inefficient preservation the supervising sections provide and the destruction tourists bring to the tourist resources have led to the great damage to our country’s tourist resources, which gradually diminish and consume the original connotations and values of the unique prospect of culture, firstly, this paper analyzes the preservation problems of our country’s tourist resources and explains the current situation of the end of the paper, it emphatically es up the measures to the preservation of the tourist resources in our words: culture;culture prospect;tourist resources;the protection of tourism resourcesII第四篇:土木工程專業(yè)畢業(yè)論文中英文摘要XX大學(xué)畢業(yè)設(shè)計(jì)(論文)摘要本文主要針對(duì)新建鐵路精伊線莫仁至阿恰勒段的初步設(shè)計(jì)及相關(guān)程序設(shè)計(jì)。設(shè)計(jì)的具體內(nèi)容由以下幾個(gè)部分組成:結(jié)合地形、地質(zhì)條件,在帶狀等高線地形圖上,按初步設(shè)計(jì)的步驟,選定線路的基本走向,并進(jìn)行路基設(shè)計(jì),包括線路的平面定線、平面設(shè)計(jì)、縱斷面設(shè)計(jì)、橫斷面設(shè)計(jì)、路基土石方計(jì)算程序設(shè)計(jì)、平面坐標(biāo)計(jì)算程序設(shè)計(jì)、及相關(guān)外文科技文獻(xiàn)翻譯一篇。平面定線過程中,根據(jù)坡度的變化,注意緊坡地段和緩坡地段的定線要求及定線技巧,在設(shè)計(jì)過程中,由于兩站之間有較大的高程差,所以為了減少挖方量和爭(zhēng)取最大高程,線路采用較大的坡度上坡,并注意使直線與曲線相互協(xié)調(diào),充分考慮夾直線和緩和曲線長(zhǎng)度的要求;縱斷面設(shè)計(jì)中,注意最大坡度、坡段長(zhǎng)度、坡段連接與坡度折減等問題,在變坡點(diǎn)處應(yīng)合理設(shè)置豎曲線 ;在平面坐標(biāo)計(jì)算程序設(shè)計(jì)中,對(duì)兩種方法進(jìn)行比較,采用Fortran語言編制計(jì)算程序;在橫斷面設(shè)計(jì)過程中,考慮曲線地段路基面加寬等問題。整個(gè)設(shè)計(jì)分幾個(gè)階段進(jìn)行,每一階段的工作都需要綜合考慮、精心設(shè)計(jì)。設(shè)計(jì)的前后都要進(jìn)行必要的比較、檢算,符合標(biāo)準(zhǔn)以后,提交有關(guān)設(shè)計(jì)成果,完成設(shè)計(jì)。關(guān)鍵詞:平面縱斷面豎曲線路基橫斷面XX大學(xué)畢業(yè)設(shè)計(jì)(論文)AbstractThe article aims in designing newbuilt railway preliminarily for JingYi line from Moren to Aqiale section and relevant concrete contents of the design are as follows : Following the procedures of preliminary design , bine the topography、geology condition , select the basic trend of the line on the topographic map of belt contour , and start the subgrade design,including level location、level section design、profile design、cross section design、subgrade cubic meter of earth and stone calculation p
