Structural characteristics and dynamic mechanical properties of granite residual soil based on dynamic triaxial tests

Yantu gongcheng xuebao
The granite residual soil is a typical soil widely distributed in the coastal areas of South China and other rainy regions. Due to its unique geological formation, it exhibits both high strength and large porosity, making it widely used in underground ...

Long-term geomechanical behavior of geogrid-reinforced ballast in dynamic triaxial tests

Soils and Rocks
During operation, the ballast is subjected to a gradual breakage process that causes clogging of the substructure. Intervention periods on the ballast layer generate high costs that impact the long-term competitiveness of railways. In this context, this work aims to evaluate the geomechanical behavior of reinforced ballast, assessing the effect of ...
