Therefore, before construction, sufficient preparation must be made to survey the local geology so as to comprehensively grasp the specific foundation condition and provide necessary basis for later design. In foundation management, the problem of soft soil foundation is common and is usually the subject of intensive research. The soft soil has a large water content and a large gap, so that the strength is low, the bearing capacity is weak, and some safety problems are often caused.
The soft soil foundation is mainly composed of clay, and has high compressibility and poor soil quality. In addition, peat, sand, etc. are also main components of soft soil foundations. The larger and looser gaps often adversely affect the compactness of the filled soil. When the foundation trench is excavated, the foundation bearing capacity is weak due to insufficient soil strength, and the foundation bearing capacity is high in compressibility, so that the phenomena of sliding and sedimentation often occur, and the stability cannot be guaranteed. In order to enhance the bearing capacity of the engineering, some effective means must be adopted to treat the soft soil foundation so as to ensure the quality of the whole engineering. The method for treating the soft foundation mainly comprises the following three methods:
1. a soil replacement bedding course method: the soil changing cushion layer method is to dig out the soft soil under the basement, change some materials for filling, and tamp the soil. 2. And (3) a method for reducing the underground water level: the method mainly pumps underground water to generate an underground water level gradient, so that the underground water level is reduced, and the economy and the safety of the bank protection project are ensured. 3. Pile foundation treatment: the strength of the soft foundation is increased, and the stability of the foundation is improved. The compressibility of the soil is reduced, and thus the settlement and uneven settlement of the foundation are reduced.
