Abstract:

Based on the field test data of Shuo Huang heavy haul railway subgrade and the reinforcement mechanism of inclined high pressure jet grouting piles (IHJGP), a study was made of the comprehensive reinforcement effects of this technology. Studies show that the strength, the stiffness, the bearing capacity and the soil compactness of the subgrade reinforced by IHJGP improves significantly, which proves that IHJGP is an effective reinforcement technology for the existing railway embankment.

Key words:existing heavy haul railway; subgrade strengthening; inclined high pressure jet grouting pile; evaluation of reinforcement effect
