Research On The Annual Production And Consumption Of The Maintenance Project Of The Highway Bridge-culvert In Shaanxi Province

In recent years,the rapid development of highway in China at the end of 2018,the national highway mileage reached 4.9175 million kilometers,of which the highway 142600 kilometers,the construction of basic saturated state,after the center of gravity shift from new to custody,bridge maintenance as the key link of the highway maintenance,to ensure road smooth general characteristic,security,rapidity of decisive significance.However,at present,due to the lack of relatively uniform pricing standards in the maintenance market,it is difficult to calculate the amount of works in the bidding process,which also makes it difficult for engineers to accurately construct Bridges and culverts during minor maintenance,affecting the overall maintenance progress of the expressway.Based on the sorting summary 20 highway in shaanxi province of fabricated small box girder bridge minor repair and maintenance quantity of calendar year,analyzed the bridge culvert of quantities and fixed number of year of the traffic,traffic,environmental factors such as climate,building Bridges minor repair quantity time-series forecasting model,clear in northern shaanxi,the guanzhong,three regional benchmark price,establish cost consumption index and coefficient of pricing,design of different types of bridge culvert minor repair and maintenance engineering minor repair maintenance of quantities per kilometer,and extend to predict the future years of bridge culvert minor repair engineering cost consumption,promote shaanxi province highway maintenance work,make contributions to "7918 network" highway construction.
