=Su (los yog qee zaum cu), lub zog tsis muaj zog. Nws yog feem ntau saws nyob rau hauv txwv qhov sib npaug ntsuas qhov twg tus nqi ntawm kev thauj khoom yog ntau dua li tus nqi ntawm cov dej pore pressures, uas yog tsim los ntawm kev txiav txim ntawm shearing av, yuav dissipate.
Yuav ua li cas undrained shear zog qhia rau koj?
Drained lub zog ntawm cov tsis yog txiav txim rau lub sij hawm ntev stability ntawm txiav slopes. undrained shear test: nws yog tus nqi siab tshaj ntawm kev ntxhov siab nyob rau hauv kab rov tav.
Yuav ua li cas koj thiaj paub tias nws ntws los yog tsis muaj dej?
Raws li koj txhua tus paub hauv qhov dej ntws tawm, cov dej pore tuaj yeem yooj yim ntws tawm ntawm cov av matrix thaum nyob hauv qhov tsis muaj dej, cov dej pore tsis tuaj yeem ntws tawm lossis tus nqi thauj khoom sai dua li tus nqi ntawm qhov Cov dej ntws tawm tuaj yeem ntws tawm.
Dab tsi yog qhov txawv ntawm undrained shear zog thiab cohesion?
Raws li kev tshuaj xyuas uas undrained shear zog coincides nrog 50 feem pua ntawm cov ntaub ntawv xa tawm tib lub sij hawm undrained compressive lub zog yog ncig ob zaug ntawm cohesion rau kev sim siv lub siab tsis muaj kev txwv. Qhov kev sib raug zoo no yog qhov sib npaug uas paub zoo tshaj plaws.
Qhov tseem ceeb ntawm shear zog ntawm av yog dab tsi?
Shear Strength Shear zog ntawm ib av yog lub peev xwm ntawm cov av los tiv thaiv shearing stress. Nws tseem yog ib qho tseem ceeb heev nyob rau hauv txoj kab nqes stability ntawm lub ntiaj teb embankments thiab khaws cov phab ntsa. Rau lub hom phiaj no kev sim triaxial yog qhov tsim nyog tshaj plaws.
