Research On The Soft Foundation Treatment Of Daqing Oilfield Roads

Since China’s reform and opening up, both national productivity and economy have developed rapidly. Also, livelihood projects are increasing continuously. Therefore, the scale of urban road construction is expanded. The underground structure of city is rather complicated so that the difficulty of road constructing projects is getting higher and higher, and the requirement of soft foundation treatment is further improved. If the soft foundation treatment method is dealt with improperly, it will lead that the road base is unstable, and road’s life cycle is reduced. Soft base, bearing capacity of road foundation is weak, in urban road constructing projects is a common problem. If this kind of problem cannot be dealt with correctly during the road construction, it always leads to unstable foundation, road crack, dislocation between roads and bridges, etc. In very severe cases, it leads the entire roads are unavailable.The quality of soft foundation treatment is closed connected to the quality of the entire road. Therefore, effective treatment on road foundation is required. However, road foundation treatment is always effected by limited constructing conditions, low embankment, short construction period, environment limit, and other problems. In Daqing’s urban road construction, soft foundation treatment has become a significant key to solve problems of short life and low quality. Therefore, it’s important that soft foundation of urban roads has to be dealt with correctly. During the construction, Strict quality control is required, and do a good job on every detail. Based on the actual situation, adopt correct techniques and deal with scientifically and reasonably.To, guarantee the effect of soft foundation treatment of urban roads, this paper focuses on the application of soft foundation treatm ent on urban roads and researches on common used methods of soft foundation treatment on urban roads at home and abroad. According to the road condition in Daqing, th e cold recycling, replacement method, reinforced gravel, and other soft foundation treatm ents are analyzed and com pared in this paper. Furthermore, the feasibility study report of soft foundation treatment in Daqing, is achieved by optimizing the method of soft foundation treatm ent so that the efficiency and quality of the soft foundation treatment is improved, and it contributes that Daqing annual output by 40 million tons.
