undrainedwet depositionThe effects of confining pressure, relative density and sample preparation methods on the shearing strength of Chief sand were studied. Results are presented of drained and undrained monotonic triaxial compression tests, performed on samples with initial densities of 0.29 and 0.80,...
A clear increase in undrained shear strength was observed for specimens sheared after drained heating to an elevated temperature, while a further increase in undrained shear strength was observed for specimens sheared after a drained heating-cooling cycle. This is attributed to the permanent decrease ...
Effect of grading characteristics on the undrained shear strength of sand: review with new evidences In this paper, the shear strength of saturated pure sand and sand–silt mixture is evaluated by monotonic undrained triaxial tests that were carried out on... E Bayat,M Bayat - 《Arabian Journal...
2.For it′s creep behavior,undrained shear strength of saturated clay is related to load rate.由于流变特性的影响,饱和粘土的不排水抗剪强度与加载速率有关。 3.New soil classification chart and undrained shear strength ( c u) based on CPTU are developed in this paper.:孔压静探试验 (简称 CPTU...
Stress-strain behavior and liquefaction strength characteristics of Ottawa F65 sand Monotonic drained and undrained triaxial tests shed light on the steady-state (critical state) of Ottawa sand, while stress-controlled and strain-controlled cyclic triaxial and direct simple shear tests provide key informa...
2) unconsolidated and undrained triaxial shear test 不固结不排水剪试验 1. The methods on unconsolidated and undrained triaxial shear tests are different in the testing codes and textbooks in China,and they produce different results: the shear strength of homogeneous saturated normal consolidated soil...
