AI Technical Summary
The existing simulation test results of roadbed defects lack authenticity, and different test chamber sizes and material treatment methods affect the stability and dispersion of test results, making it difficult to accurately assess the injectability, controllability and economy of repair materials.
Using a test chamber and load plate with a specific ratio (4≤B/d≤6), combined with a servo hydraulic loading system and an intelligent data acquisition module, a grouting repair test for subgrade defects was conducted by simulating the formation process of real subgrade defects. This included material compaction, defect simulation, detection, and grouting repair.
It achieves stability and reliability of test results, with small dispersion of bearing capacity data, enabling more realistic simulation of subgrade distress, evaluation of the effectiveness of repair materials, cost savings and improved evaluation efficiency.
