Feasible Study On Jiutai To Kaiyuan Highway Project

Engineering in the highway needs to throw in a great deal of manpower, material resources and financial power, is a huge engineering.The success or failure of engineering in the highway involves to follow a line region economy, politics, ecoenvironment etc.many factors.So, how the possibility of correct engineering in the valuation highway, follows economy, political in the line district to have to the pass important function to investment efficiency and highway of highway.Therefore, according to the relevant rules of the national law and the transportation department, , while lately setting up, changing to set up and extending a highway, have to carry on a research analytical the engineering possibility of constucting the item.This text divides seven chapters and mainly carry on an engineering possibility to that item from 5 research analytical.1.the traffic volume predictAt in detail research influence area economy the development and transportation develop the foundation of relation up, pass to the survey analysis(include a transportation survey analysis) that influences net in the highway inside the area and originally possessed history presents condition in the highway, consider in the meantime economic development in the future to follow line economy the development and transportation promote function etc. factor, adopted a flexible coefficient method to carry on an estimate to the traffic volume, knew well to see form.2. constuct standard and scaleThe result that predicts according to the traffic volume, principle constucts standard and traffic volume to mutually adapt to according to the highway, synthesize consideration to follow linear of conditions, such as geography, geology and weather...etc., and this item is in the position and the function in net in the highway, recommend originally item Sijiazi to Qiandongjai adopt one class highway standard, design speed is 100 kilometers of one hour,Qiandongjia to Shuangyang segment adopt a second class highway standard, design speed is 80 kilometers of one hour.Pass analysis compare, this item recommends the alignment of project for:Sijiazi rise and follow Xiyingchengzi to Ponihe, Guanting,Wanchang, to south through Yinmahe,south though Changling,Songjaiwa,Lishuyuan,Yujiayun,after finally crossing over a Wu to this item terminal point.All of the route grows 92.87 kilometers.The another construction links line 1 get up Shuangyang area conjunction, length is 1.48 kilometer.The route total alignment from north to south.3. construction project the ratio chooseAccording to the concrete circumstance of this item and combine the condition of existing highway along with the line geography, geology condition, the route big parts of road segment follow existing cloth line in the highway, the partial road segment carries on an appropriate improvement, the whole lineses route project ratio that hasn't carried on big scope chooses a work.Passes main town road to the route segment, drafted to make use of an old road project and round more project, and carry on comprehensive comparison, in addition to wave the mire river town and double in addition to sun area, the other road segment all recommended to cover little, break a small old road project to the environment.4.the investment estimate and the economy analyzeAccording to nation of relevant stipulate, estimate this item construction to invest 669,527,100 dollars, each one costs to 7,209,100 dollars.The item construction investment adopts application bank to lend money 430,000,000 dollars, item legal person self-raised capital gold is 239,527,100 dollars solution.The construction expects to concretely arrange to start work for 2009, completes work in 2010 and constucts to expect for two years.According to nation relevant stipulate, this item carried on finance evaluation and national economy evaluation, the analytical result enunciation, the item finance internal rate of return and economic internal rate of return were aller high than for 6.46% and 12.96% respectively nation rules of index sign, the item has better economic efficiency and social efficiency and sees is all viable from the angle of the national economy and the finance, and have stronger anti- risk ability.5. comprehensive conclusionPass the analysis to economy, transportation and net present condition in the highway of this item society in the place district and the future development trend, at well the foundation of survey and comparison argument up, act according to the relevant rules of nation and Jilin province, recommend this item to adopt one respectively class and second class highway standard.Saw from the result of analysis argument, this item recommend of route project and main engineering technique project could go, the item could provide a good conveyance infrastructure for user in the highway after being built up and had high direct efficiency and better indirect efficiency, society influence smaller, the risk is lower, from the national economy and the finance angle, this item is all viable...
