[0002] Soft soil roadbed refers to a common type of roadbed in special areas. It requires special design and treatment. It is mostly distributed along rivers, streams, ocean coasts, inland lakes, ponds, basins and rainy mountain depressions. Soft soil has the characteristics of high water content, poor permeability, low natural strength and high compressibility. If the critical height is exceeded, the foundation will lose stability. Common treatment measures for soft soil foundations include soil replacement, drainage sand cushion layer, counter-pressure berm, riprap and silt squeezing, cement soil mixing, surface reinforcement with civil engineering fabrics, and sand well reinforcement. However, the existing reinforcement methods will have the following problems after reinforcement:
