Research On The Feasibility Of Yushu To Songyuan Expressway Project

Project Feasibility study predict project profitability from perspectives of technology and economy.It predict the profitability after development to demonstrate the necessity of project,improve construction's scientificity and reliability,reduce uncertainties during project development,and enlarge general profitability for the project.This paper uses the Yushu-Songyuan road as an example to demonstrate the project feasibility study from perspectives of technology,economics,and society.The study showed: based on investigation of regional social and economic situation influence,and transportation volume,the relationship with space and time was obtained.The study uses the four-step method to estimate the trend and prediction.The conclusion is: by 2034 the average vehicle traffic volume will be 39,494 vehicles per day.Based on road engineering manual,this paper determined road grade,design speed,road width etc.Then based on site investigation,terrain,geology,hydrology,meteorology,four alternative designs are proposed.Comparing the pros and cons,the recommended design was developed.Then assessing the investment amount and economic feasibility,the study demonstrated the project feasibility.The feasibility study of this project is the key guidance of the Yishu-Somgyuan Road but can be used as reference nationwide.
