Soft ground is not a bad foundation. As the strength of soft soil with a low compression features such as high and low permeability, often unstable or excessive settlement, leading to damage or can not properly apply the foundation, and therefore the construction of buildings on soft ground, we must attach importance to the foundation of deformation and stability. In the weakness of land-based buildings tend to occur on the foundation of strength and deformation can not meet the design requirements of the problems, which often need to take measures to carry out ground handling. The purpose of treatment is to enhance the strength of weak foundation to ensure the stability of the foundation to reduce the compressibility of soft soil, reduce the basis of settlement and differential settlement. Current weak foundation for the various elements of many different approaches, the following is common in several ways.
Key words: soft foundation, improve strength, stability, and treatment methods
