When the cylindrical roller is fixed in the soil and rolling continuously, a certain theoretical analysis is required. Firstly, it is necessary to understand the physical and mechanical properties and mechanical parameters of foundation soil, including soil density, compression modulus, shear modulus, internal friction angle, etc. Then, the material, shape, size and rolling speed of the roller need to be analyzed to determine the force and rolling state of the roller. Finally, in combination with the interaction between soil and roller, the equivalent uniaxial stress intensity method, contact pressure superposition method, finite element method and other methods can be used for theoretical analysis, and the results of roller stress distribution, soil stress field, deformation field and stability analysis can be obtained. It should be noted that many factors such as the deformation of the contact surface, the contact area and the viscous force between the soil and the roller should also be considered in the theoretical analysis. In this regard, it is recommended to refer to the "Foundation Engineering Manual" and "Soil Mechanics" and other professional reference books, carry out theoretical analysis according to the specific situation, and improve the construction quality and safety.

First, it is necessary to determine the nature of the soil, whether it is clay or sandy soil, and the water content in the soil. Then, according to the material, size, load and other parameters of the cylindrical roller used, combined with the soil mechanics theory, theoretical analysis can be carried out by calculation, simulation and other methods. If more specific analysis is required, it is recommended to refer to relevant building engineering design specifications and geotechnical data. It should be noted that the interaction between the soil and the cylindrical roller should be considered in the analysis process, and necessary corrections should be made according to the actual situation.
