The Highway Design Of The Xinjiang Gobi Desert And Grassland Area

With the development of social economy and in order to promote the speed of commonprosperity of the whole nation, the highway extends to the area of xinjiang gobi desert andgrassland. The terrain, geology, environment and climate of xinjiang gobi desert and grasslandarea are complicated. The highway of the area xinjiang gobi desert and grassland is justbeginning, the study and the theories are not very mature from the current collection andinvestigation. It must be cause many problems if the design of the route is according to thehighway design standards and specifications, such as the economy and the constructiondifficulty decrease a lot, so it can’t be designed according to the general areas’ design indexand concept.This article selects the desert of Xinjiang area and makes the linear indexes, trafficinvestigation and statics, from which, we can get that the straight line is in the majority, morethan1/2of the highway mileage, the gradient is minimum, the car is mainly in transit, thepoint of the profile change little, the actual speed is bigger than the design velocity, etc. Andalso there is some forecast for the traffic volume of the xinjiang gobi desert and grasslandarea.As the area of xinjiang gobi desert and grassland, which needs the cars’ drivingperformance, this article makes some instructions and summary. And in view of the xinjianggobi desert and grassland area’s linear, the driving indoor simulation experiment was carriedout, from this we get the relationship between the drivers’ physiological indexes and route.This article based on the climate, terrain, geology, environment, economy and population ofthe xinjiang gobi desert and grassland area, and combines the cars’ driving performance andthe drivers’ physiological comprehensive factors to study the highway design of the xinjianggobi desert and grassland area and put forward the related technical index. There is muchsignificant reference for the highway design standards of the xinjiang gobi desert andgrassland area.
