Talking about the Quality Control of Collapsible Loess High Fill Roadbed and the Special Roadbed Treatment Construction Scheme

During the construction of collapsible loess high-fill subgrade and special subgrade, it is easy to cause subsidence due to the influence of the soil layer and geological factors in the area, which will affect the construction schedule and overall quality. Based on this, effective quality control measures need to be taken to improve regional soil layers and geological defects to ensure the orderly construction. This article combines specific construction cases to analyze the quality control of high fill and special subgrade projects in collapsible loess areas, with a view to providing reference for similar projects.
