For the difficult problem of the quality testing of grouting, laboratory test, dynamic penetration test and geological radar test method were used to measure the reinforcement effect after grouting throughout grouting model test and it was found that mechanical parameters and bearing capacity were increased and the continuity and integrity were improved, which was compared with the real results reflected by the full section excavation. The results show that the bearing characteristics and the slurry distribution patterns are basically the same in both. The soil physical and mechanical properties are significantly improved, and soil stabilization enhances, continuity and integrity are improved. Integrated laboratory test, dynamic sounding test and geological radar test method can better reflect the grouting reinforcement effect in loose soil, and offer certain reference and guidance for the grouting effect detection in loose filled soil.
