The Analysis On The Constructing Cost For Filling Subgrade In Aeolian Sand By The Method Of Wet Compaction In Hunsnhandake Sandlot

Along with the enlargement in scale and the unceasing elevation in rank, the Desert highway in China have been giving an impulse to our country's traffic transportation and economy, as well as bringring benefit to the local people. At present,the cost and ration of construction of Desert highway have aroused highly attention of all departments and construction units. The present construction quota is not suitable to apply to Desert highway directly, therefore, how to calculate the cost of constructing the Desert highway has become a main problem in estimation of cost and in recruiting bid.This paper, by doing research on the desert highway X-501 line which is from bairiwula to wulanchabu highway in Xilinguole League, and by collecting research data indoor and construction time of each working procedure of filling subgrade of aeolian sand, analyzed the construction cost of subgrade.1) Through analyzing the existing influence of aeolian sand upon construction cost of Desert highway in Hunshandake desert, this paper indicated that the uniformity coefficient, the curvature coefficient, the optimum water content and maximum dry density are the influencing indexs to the construction cost of aeolian sand Desert highway.2) According to the partial and correlation analysis, among working procedures, the optimum water ratio has a major influence on constructing cost of watering process. Moreover, the uneven coefficient and the optimum water ratio both have a great effect on the constructing cost of steady press, the vibration press's constructing cost is mainly influenced by the uneven coefficient and the uneven coefficient, the curvature coefficient and the maximum dry density have a great impact on the final stress constructing cost while the optimum water ratiot has little.3) The construction cost regression model of Hunshandak aeolian sand's filling subgrade is established by Correlation and regression analysis, and analyzed the influence of aeolian sand's feature upon construction cost by using the model. The experimental reperimental results indicate that thosemodels can reflect the changing law on the the construction cost in the process of aeolian sand's filling subgrade that haa been influenced by aeolian sand's feature.
