According to the research results and information of indoor tests and field tests, the weak to highly weathered argillaceous siltstone physically improved soil of Wu-Guang (Wuhan-Guangzhou) High-speed Railway was studied using wetting-drying cycles compaction, resonance, critical dynamic stress, dynamic shear strain parameters, and so on, to comprehensively evaluate the dynamic stability of soft rock improved soil. The results show that the long-term dynamic stability of the weak to highly weathered argillaceous siltstones physically improved soil meets the requirements. Dynamic shear strain m...
