According to the basic principle of geocell, the bearing capacity of the foundation is determined by the shear force along the sliding line and the forces in the active, transitional, and passive zones of movement. The true process of the above principle can be clearly experienced not only on sand bases, but also on soft foundation highways, although its formation rate is slower than that on sand. Even with better roadbed materials, lateral movement cannot be avoided. The roadbed of a typical highway is several meters above the ground, making it difficult to absorb water and turn over mud, but long-term settlement still exists. Upon investigation, rainwater infiltration, material loss, and foundation subsidence are some of the reasons. The lateral displacement of materials towards both sides of the roadbed section under long-term wheel load and vibration force is undoubtedly another very important reason for the roadbed and pavement. Taking various levels of highways in our province as an example, it can be clearly felt that an "S" - shaped groove has been formed on the main lane of the road. Some highways are no exception, and the bumps of cars driving on the lane are significantly stronger than the feeling of driving on the overtaking lane, especially in the road bridge connection section.
