Study On Treatment Measures Of Soft Foundation In ? Highway In Northeast

In the construction of highway, because of the lack of basic body bearing capacity of the road, there are a series of diseases, such as settlement, deformation and so on, which seriously affect the quality of the road, which is not conducive to driving safety. In order to ensure Ali River to Jiagedaqi highway smooth construction and ensure the road traffic safety and smooth, should adopt the measures of highway soft soil foundation for its.Through introduced Ali River to Jiagedaqi highway engineering, involved in the project and the properties of soft soil were analyzed and from moisture, soil permeability, compressibility, shear strength, the strength of soil and so on several aspects of soft soil engineering properties research, after the paper selects reasonable control measures were applied to provide the basis. In order to select a reasonable approach, from the aspect of the engineering cost, construction time limit for a project, scope of application, carrying capacity, and for comparison, combined with the Ali River to Jiagedaqi highway soft soil foundation,selected Foundation Replacement and Impact roller to solve the problem.The Ali River to Jiagedaqi highway selected measures of detail, from construction technology, construction attention items and quality assurance measures are discussed in detail, that really feasible quality assurance measures and key control points, to provide technical support for the engineering entity.In order to verify the Ali River to Jiagedaqi highway soft foundation treatment measures of rationality, the development of field settlement observation scheme, the settlement measurement, then the growth curve method for post construction settlement prediction. Finally, the differential settlement control standard on treatment effect was evaluated, based on Evaluation rationality of soft soil subgrade treatment scheme.
