一种高含水表土覆层窄域建筑物分级承载协同保护方法
By using a two-layer graded bearing system and a graded stress-controlled settlement method, the problem of easy failure of a single bearing structure is solved, achieving stable protection of high water content topsoil cover layers, adapting to large deformation characteristics, reducing engineering workload and ensuring long-term stability. It is suitable for the protection of immovable buildings under high water content topsoil cover layers.

AI Technical Summary
Existing interlayer gap filling technologies suffer from the following problems: single-bearing structures are prone to failure and have poor adaptability. They cannot adapt to the large deformation and uneven settlement characteristics of high water content topsoil layers. Furthermore, the grouting diffusion is out of control, resulting in insufficient long-term stability and making it difficult to protect ancient buildings and sensitive structures.
A two-layer graded bearing system is adopted, including an interlayer anti-deformation interlayer and an auxiliary buffer interlayer. By monitoring surface subsidence data, a graded bearing structure is constructed, and an early warning threshold is set to fill the gaps between the layers, thereby achieving graded stress and settlement control, reducing the amount of engineering work and improving long-term stability.
It enhances resistance to breakage and fault tolerance, adapts to the large deformation characteristics of high water content topsoil cover, reduces protection costs, ensures that surface deformation is within the range of very minor damage, achieves full-cycle quality control, and is suitable for the protection of immovable buildings under high water content topsoil cover.
