Reinforcement of Clay Soils through Fracture Grouting

Fracture grouting is widely used for building foundation reinforcement, however the underpinning mechanisms are still not clear. Using numerical results about a single-hole fracture process as basis, model composed of soil and veins has been created to analyze reinforcement mechanism. The influence weights vein skeleton compaction effect have studied, thereby obtaining relevant information on compressive modulus considered composite soil. research show that plays leading role in reinforcement. pressure, hardened modulus, shape all
