三轴剪切过程中排水条件对钙质砂颗粒破碎、变形和强度特性的影响OA北大核心CSTPCD
Effect of drainage conditions during triaxial shearing on particle breakage,deformation,and strength properties of calcareous sand
钙质砂的颗粒破碎、变形和强度特性与受剪时的排水条件有关.然而当前的研究很少考虑不排水剪切过程对钙质砂颗粒破碎和力学特性的影响.对不同初始相对密实度的钙质砂进行了一系列不同有效围压下的三轴固结排水和不排水剪试验,以研究剪切过程中排水条件对钙质砂颗粒破碎和力学性质的影响.结果表明:在相同的有效围压下,排水剪试验的颗粒破碎率高于不排水剪试验.在排水剪与不排水剪过程中,钙质砂的应力-应变曲线都表现为应变软化行为,其剪胀趋势受到初始相对密实度和有效围压的影…查看全部>>
The particle breakage,deformation,and strength properties of calcareous sand are related to the drainage conditions during shearing.However,the effect of undrained shear processes on the particle breakage and mechanical properties of calcareous sand are rarely considered in the current studies.A series of consolidated drained and undrained triaxial shear tests is conducted on calcareous sand with various initial relative densities under different effec…查看全部>>
