Triaxial testing size sample
WebOverall, triaxial tests are a powerful tool that can provide valuable insight into the strength and behavior of soil and rock materials. When planning a triaxial test, it is important to select an appropriate specimen size, design the test to accurately simulate the loading conditions that will be encountered in the field, and take care to ensure that the test is conducted … WebStrainburst is one type of rockburst that generally occurs in deep tunnel. In this study, the strainburst behaviors of marble specimens were investigated under tunnel-excavation-induced stress condition, and two stress paths were designed, a commonly used stress path in true triaxial unloading rockburst tests and a new test path in which the intermediate …
