| Abstract: | In order to study the granular soil's rheological properties in embankment,a new axial and confining pressure providing equipment for large triaxial rehological tests were presented.A large triaxial rheological testing system(named GSRT) for granular soil was developed with the new axial and confining pressure providing equipment to surmount the load permanence and stability defect in large triaxial rehological tests,on which the granular soil samples with the large dimension and large diameter grain in the soil sample can be experimented.The development of this large triaxial rheological testing system(named GSRT) provides the testing tool to study the granular soil fillings' rehological properties in road embankment. |
| Keywords: | large triaxial rehological apparatus granular soil embankment fillings triaxial rehological test axial load in triaxial rehological test confining load in triaxial rehological test |
