Soft Soil Subgrade Treatment Research In Tianjin Binhai New Area

Tianjin Binhai New Area belongs to the typical coastal soft soil ground, With large water content , Plastic flow state, large compressibility, little cohesive force and small internal friction Angle . By summarizing the characteristics of the soft soil ground, it will form a set of effective methods for the coastal areas. In this way , this is advantageous in simplifying the pre-project preparation works, reducing the cost of engineering, guaranteeing the project security. At the same time ,it will achieve the most optimized benefit.This paper starts from identifying types of soft soil, it research the coastal area of the subgrade engineering survey points and soft soil subgrade settlement and stability calculation method , In this paper ,it concrete analysis of soft soil subgrade treatment measures of application.Secondly, The paper summarizes some soft soil subgrade treatment methods, Finally this paper summarizes the characteristics of soft soil subgrade , the key factors in subgrade treatment, and puts forward a set of effective treatment plan.
