Research On The Key Technology Of The Hu Ning Highway Extension

With the development of economy, the highway construction in China of1990’s into aperiod of vigorous development. In recent years, increasing traffic, highway reconstructionproject has become a hot issue in our country highway construction project. However, due tothe design and reconstruction engineering construction project is different, at present has notyet formed perfect design standards and specifications, and key technology in highwayreconstruction project for research work is of great urgency.Existing highway reconstruction project is presented in this paper, on the basis ofcombining modern exploration design technology and method of highway, the road conditionevaluation of highway reconstruction and expansion of the form and the expansion of thescheme selection, engineering splicing technology, and the traffic organization in the system.Main research results are as follows:(1) Proposed to transport corridor of highway traffic volume prediction method, thereconstruction and expansion in Hu Ning expressway for example, on the highway trafficcapacity and service level evaluation before and after the reconstruction, on the basis ofbuilding construction and highway traffic RCQI evaluation index system;(2) In reconstruction of existing highway engineering practice, on the basis of the studyof highway reconstruction method, and unilateral splicing, single plane separation, stitchingon both sides, bilateral plane separation, and combined the advantages and disadvantages offive kinds of highway expansion design scheme comparison. Constructing fuzzycomprehensive evaluation of highway expansion project selection model, and applies themodel on the choice of huning expressway reconstruction programme work；(3) In highway reconstruction project of principles, methods and steps of trafficorganization study and comprehensive traffic organization scheme, gives the network layerand to evaluate the scheme. Will network layer traffic organization scheme used in Hu Ningexpressway reconstruction project of traffic organization in the process of work, practiceprove that the effect is ideal.In this paper, the research work of expressway reconstruction project provides technicalsupport; to our country highway reconstruction project development has a certain role..
