Abstract 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 grouting process as a basis, a model composed of soil and grouting veins has been created to analyze the reinforcement mechanism. The influence weights of the grouting vein skeleton and compaction effect have been studied, thereby obtaining relevant information on the compressive modulus of the considered composite soil. The research results show that the compaction effect plays a leading role in the soil fracture grouting reinforcement. The grouting pressure, the hardened grouting vein modulus, and the… More >
