Abstract: On the base of having given a deep analysis on composition and structure of soil,drawing a conclusion that the principle of soil stabilization is enhancing the strength of joints among soil particles and improving the contact of soil particles, proposing that the key technology of increasing the soil strength is chemical reaction occurring between bonding materials and soil particles.And summarizing some important technical methods of soil consolidation.Moreover analyzing the method of soil consolidation agent which is often used at present in soil stabilization and probing into some kinds of soil consolidation agents.At last,analyzing some important factors that influence the stabilizing soil durability such as shrinkage,water resistance,freeze-thaw durability.
